“All email clients suck, this one just sucks less!” Quote from the lead developer. Checking email requires a web-based front-end or a separate mail client. These require graphical environments, with few exceptions. Neomutt is one such exception. With Neomutt, you can check your emails on the command line in a separate application. You may be limited when it comes to web-based emails, but there are workarounds also for that inconvenience.

The basic ideas

To understand, you need to understand the basic concepts. The main one is the views you have for each job; listing the mails and reading each mail.

Index

Neomutt starts with the Index Screen. This shows all emails listed the way you want. Whether you see read emails or not, you can set yourself. The default behaviour is to show all emails even when they are marked deleted; you later move them to trash. You choose an email with arrows, vim keys, or what you specify yourself in the index screen. To open them, hit enter and they will appear in the Pager screen.

Pager (Showing the Emails)

In the pager, your emails will show. In the basic form, you will only see text-based mails. To see HTML, you need to designate your web browser and have Neomutt call it up. Neomutt will make a temporary file that contains the corresponding web page that is the email.

Sidebar

The sidebar keeps all the mailboxes you have available, there can be many! You can choose to have this, not have it or toggle it with a key-binding. Most users will have a key-binding, like ‘B’, for example.

Navigation

You navigate your inbox with the arrow keys and scroll down emails with the space bar. To delete the email, you use ‘D’. All these things are common, and you can set them yourself with the configuration file. The interesting part is that you need to know the index and the pager. When you configure neomutt, the settings will be according to which view you use. Most of these will be for both views.

Binding keys

In neomutt, you will work with the keyboard exclusively. It is a terminal-based application, after all. For this reason, you will want to bind different keys to the functions you use the most. Earlier, you could read the standard bindings; if you want to change something, you need to bind them your self. To bind capital ‘B’ to toggle the sidebar, for example, use the below code.

The list will end up fairly long so sourcing a separate file for the key-bindings is a good idea. The format is pretty simple; a capital letter means exactly that. To show Ctrl-x, you put \c-x

Connecting an account

The first thing you need to do is to connect an account. You can do this with one command at a time; you will need up to twenty commands to get to your mailbox. Not what you want to do daily. It can be helpful when you try to set up a new account. In ordinary use, you want to have the account open when you start neomutt. This requires a configuration file. In the file, you will need to set all the values for the account.

The parameters are pretty simple to understand; you may have different passwords for IMAP and SMTP though it is rare. What can be confusing is the folder value. This configuration is for IMAP; the folder you are setting is on the remote server. You can use a local store for your emails, but that is another setup. The password is empty in this case. When you run, neomutt will ask for your password every time you start. If you set the password, neomutt will collect it from this config file. It is good practice to encrypt the file where the password is!

Web contents

When an email is written in HTML, you cannot read it with Neomutt, by default. You can access the mail in your default browser, though. On most systems, when you open an email, it will show that you cannot read HTML in the email client. When you press v, as it says in the pager, your default browser will open it. This is determined by the ~/.mailcap file. You find ‘text/html’ a semi-colon and the browser you will use in the file. On Debian based systems, it calls ‘/usr/bin/sensible-browser’. To set this value, you need to change it in ‘/etc/alternatives/x-www-browser’ and ‘/etc/alternatives/gnome-www-browser’. This is for the whole system.

Note that the last one is for your use only, in case you do not have root to your system. You can also set any other web browser only for mail. You do this by setting mailcap directly to a browser.

Conclusion

The neomutt package is very versatile, but the configuration is confusing and needs more well-explained tutorials and examples than you have seen here. With your mailbox overflowing with HTML-mails you may think twice about switching to a text-based mail pager. Consider, though, that you can use it as a filter. Most commercial emails are in HTML only, are your other emails in plain text?

As a Linux user, you might prefer terminal-based methods of sending emails with attachments. This article shows you four different methods of sending emails with attachments from the command line in Linux Mint 20.

You can use any of the following four methods to send an email with attachments from the command line in Linux Mint 20.

Note: For all the methods discussed below, attached the sample text file named abc.txt to every email. You can also attach other kinds of files, such as PDFs, spreadsheets, images, audios, and more.

Method 1: Using the “mutt” Package

The “mutt” package is not installed on Linux systems by default. So, you will first need to install this package by running the command below in your terminal:

Once the “mutt” package is installed on your Linux Mint 20 system, along with all the required dependencies, you can run further commands, as shown in the following image:

After the “mutt” package has been installed on our system, you can use this package to send an email with attachments in the manner shown below:

Here, replace “Sample Email Body” with the actual body of your email; “Sample Email Subject” with the actual subject of your email; “SampleAttachment” with the path of the file that you want to attach (you can also attach multiple files in a single email simply by mentioning the paths of all the files to be attached, separated by spaces); and “SampleEmailID” with the email ID of the desired recipient to whom you wish to send the email.

Method 2: Using the “mail” Command

The “mail” command is included in the “mailutils” package, which does not come installed on Linux systems by default. So, to use this method, you must first install this package by running the following command in your terminal:

Method 3: Using the “mailx” Command

The “mailx” command is also included in the “mailutils” package and, since you have probably already installed this package in Method 2, you do not have to install the package again. Instead, you can use the “mailx” command to send an email with attachments in the manner shown below:

Here, replace “Sample Email Body” with the actual body of your email; “Sample Email Subject” with the actual subject of your email; “SampleAttachment” with the path of the file that you want to attach (you can also attach multiple files to a single email simply by mentioning the paths of all the files to be attached, separated by spaces); and “SampleEmailID” with the email ID of the person to whom you wish to send the email.

Method 4: Using the “mpack” Package

The “mpack” package is also not installed on Linux systems by default. You can install this package by running the command below in your terminal:

Once the “mpack” package has been installed on your Linux Mint 20 system, along with all the required dependencies, you can run further commands, as shown in the following image:

After the “mpack” package has been installed on our system, you can use this package to send an email with attachments in the manner shown below:

Here, replace “Sample Email Subject” with the actual subject of your email; “SampleAttachment” with the path of the file that you want to attach (you can also attach multiple files to a single email simply by mentioning the paths of all the files to be attached, separated by spaces); and SampleEmailID with the email ID of the person to whom you wish to send the email.

Conclusion

By using any of the four methods discussed in this article, you can conveniently send as many emails with attachments as you would like. These methods are quite simple and straightforward, and after installing the required packages, it just takes a single command to send an email with an attachment via the command line. With these commands at your disposal, sending emails with attachments could never be easier than via the terminal.

There are many hosting companies which are providing the free version. Till yet, the people who take businesses seriously, take benefit of the flexibility and power of professional email services. So, the emails which they sent professionally are managed by a separate or dedicated mail server.

Delivered-To: ivana[at~]smartlation.com
Received: by 2002:a05:620a:1461:0:0:0:0 with SMTP id j1csp966363qkl;
Wed, 3 Apr 2019 19:50:15 -0700 (PDT)

The following fragment shows the email is being processed through gmail’s SMTP.

X-Google-Smtp-Source: APXvYqxLebBy88ASD/5vqLYdg+NGLv+sNymPjuOU6aQy3H1LyRbx4
8E4I9ojHNsM4Bvpa2lApZKJ

The X-Received header is applied by some email providers, in this case it is added by Gmail’s SMTP.

X-Received: by 2002:a62:52c3:: with SMTP id g186mr3128011pfb.173.1554346215815;

Wed, 03 Apr 2019 19:50:15 -0700 (PDT)

The next segment shows the ARC (Authentication Received Chain). This protocol assures the authentication validity when passing through different intermediating devices. In this case the email is sent from editor [~at]linuxhint.com to ivan[~at]linux.lat which forwards the email to ivan[~at]smartlation.com.

ARC-Seal: i=1; a=rsa-sha256; t=1554346215; cv=none;

d=google.com; s=arc-20160816;

And here is the first appearance of the DKIM (DomainKeys Identified Mail), an authentication method which prevents mail forgery by validating the sender domain name.  The previously detailed protocol ARC helps both DKIM and SPF (which will be shown below) to remain valid despite the route. This extract shows the given credentials.

ARC-Message-Signature: i=1; a=rsa-sha256; c=relaxed/relaxed; d=google.com; s=arc-20160816;

ibTg==

Here you can see the result of the authentication, as you see it succeeded, additionally to the DKIM you can see SPF (Sender Policy Framework), another authentication method to let the receiver know the sender is authorized to use the domain name shown in the “FROM” section.
In this case DKIM and SPF passed the authentication phase.

ARC-Authentication-Results: i=1; mx.google.com;

smtp.mailfrom="SRS0+GMs5=SG=linuxhint.com=editor @eforward1e.registrar-servers.com"

Below there is a section called “Return-Path”  and here is defined the bounce email address, which is different from the “From” section for  bouncing messages to be processed by the mail server administrator.

Return-Path: <SRS0+GMs5=SG=linuxhint.com=editor@eforward1e.registrar-servers.com>

Finally below, information on the mail server, (Postfix), DKIM version and encryption strength are displayed,

The section X-Gm-Message-State shows a unique string for two possible states: bounced back and sent.

I hope you found this tutorial on email header analysis useful. Keep following LinuxHint for more tips and tutorials on Linux and networking.

1. Roundcube

Roundcube has been around for more than 10 years, and it has since then established itself as a modern email client whose most prominent feature is the pervasive use of AJAX technology. Written in PHP, Roundcube can be easily deployed in conjunction with a LAMP stack or any of its variations that support the PHP programming language.

Roundcube is free, open source, and available in over 70 languages. It features sophisticated privacy protection mechanisms, comes with a full-featured address book with groups and LDAP connectors, canned response templates, a template system for custom skins, and it can be extended with third-party plugins.

If there is something about Roundcube that deserves criticism, it has to be the outdated look of its interface. Whereas Gmail, Outlook, and other popular email services have significantly improved their user experience, Roundcube stayed mostly the same. Some Roundcube users, however, like this because not having to re-learn how to use the client every now and then allows them to be more productive.

2. Rainloop

If you’d prefer a straightforward alternative to Gmail, with modern user interface design, complete support of IMAP and SMTP protocols including SSL and STARTTLS, and integrations with popular social media sites and cloud file storage services, Rainloop seems like the perfect choice.

Written primarily in PHP and licensed under the GNU Affero General Public License, Rainloop is simple to install and upgrade, has modest system requirements, and doesn’t require any database to work, except for contacts. Found among its many features are client-side OpenPGP encryption, keyboard shortcuts, and plugin support.

Unfortunately, Rainloop doesn’t have the largest user base, and its documentation leaves something to be desired. Even the installation instructions should be more detailed to help less experienced users make Rainloop their detail email client.

3. Mailpile

Mailpile started in 2014 as a response to Edward Snowden’s 2013 disclosures, which revealed numerous global surveillance programs, many of them run by the NSA and the Five Eyes Intelligence Alliance with the cooperation of telecommunication companies and European governments.

Mailpile can be easily installed on just about any device—from your laptop to the Raspberry Pi. Because Mailpile is supported entirely by donations, there are not intrusive and potentially dangerous ads to worry about, and your privacy is protected at all times using state-of-the-art encryption.

Even when the people behind Mailpile were just putting together a list of features the client should have, they already knew that Mailpile must perform better than popular email services in order to be attractive. It’s now clear that they’ve succeeded in achieving their goal and created what might just be the snappiest email client ever.

4. Squirrelmail

Initially released in 1999, Squirrelmail has been around for a very, very long time. Because it’s been around for so long and developed so conservatively, it falls behind all other email clients on this list in terms of its design and user experience.

There are, however, several good reasons why so many organizations still swear by Squirrelmail: it’s available for any platform supporting PHP, including Linux, FreeBSD, macOS, and the server variants of Microsoft Windows, and there are over 200 third-party plugins available for download from the SquirrelMail website that extend the client’s functionality.

If you’re looking for an email client that just works and likely doesn’t have any major security flaws, Squirrelmail is still just as good of a choice as it was when it was first released nearly two decades ago.

5. Horde Mail

Horde Mail is an email client belonging to the Horde groupware, which rests on the Horde framework. The purpose of the framework is to provide all the elements required for rapid web application development of standards-based applications capable of using existing platforms and backends.

Other applications that rely on the Horde framework include Ingo (an email filter rules manager), Sork (a collection of four account management modules), Kronolith (a calendar application), Mnemo (a note manager), Nag (a multiuser task list manager), Turba (a contact manager), and several others.

Horde Mail supports IMAP, POP3, and SMTP protocols, has native PGP encryption, comes with a WYSIWYG HTML editor for composing messages, and can download multiple attachments as a single ZIP file, just to name a few of its features.

How to Install and Configure Roundcube

In this section, we go through a very basic set up of Roundcube to give you an idea of what it involves. Our instructions are by no means meant as a replacement for the official installation guide, which is far more comprehensive. Before you begin, you should also verify that you meet all the requirements to avoid running into easily avoidable problems.

1. Download Roundcube

The first step is to download Roundcube from its official website. We recommend the Complete package as it contains all dependent packages. Roundcube is distributed as a .tar.gz file, and it’s necessary to extract it using your archive manager of choice.

2. Upload Roundcube to Your Web Server

Connect to your web server using your favorite scp or FTP program and upload the extracted files to it. The temp and logs directories must be writable.

3. Create a Database

Roundcube needs a database to work, and it supports multiple database backends, including MySQL, PostgreSQL, and SQLite.

4. Configure PHP

To work properly, Roundcube requires certain specific PHP settings. The bare minimum includes:

• Memory limit: memory_limit=64M,
• Options that control logging: display_errors=Off, log_errors=On, error_log=logs/errors.log,
• Options that control file uploads (e.g. max attachment size): upload_max_filesize=5M, post_max_size=6M,
• Options that are not compatible with Roundcube: zlib.output_compression=Off, suhosin.session.encrypt=Off, session.auto_start=Off,
• Options that control session behaviour: session.gc_maxlifetime=21600, session.gc_divisor=500, session.gc_probability=1.

Web administrators often forget about one or more of these settings, which then leads to annoying error messages.

5. Configure Roundcube

Finally, it’s time to finish your installation by visiting http://your_server_ip_or_domain/installer and following the instructions. Roundcube configuration is a complex topic as the email client has over 200 configuration options, which is why you should check this page to learn more about it. ]]> https://linuxhint.com/running-your-own-production-email-server/ Fri, 22 Dec 2017 01:23:58 +0000 https://linuxhint-com.zk153f8d-liquidwebsites.com/?p=20881 Email is hard.

You should know that up front. It isn’t for the faint of heart. Turn around and don’t look back, and all that stuff.

Now that the proper warnings are out of the way, let’s explore the most common available options in running your own email server. I’ll step through the pros and cons of each approach and hopefully give you the insight you need in making this difficult decision.

Why Run Your Own Mail Server?

Privacy is the main concern. Google scans your email to show related advertising. Even though this is done automatically and supposedly no human ever sees it, this still doesn’t sit well with some. Microsoft and others claim not to do this, but the Edward Snowden leaks about the NSA’s links to most major email providers, including Google and Microsoft, make it clear that your email with one of these providers will be scanned.

It is worth mentioning that privacy is a tricky thing to achieve in email. If you send an email to someone using Google or Microsoft’s mail servers, your communication with that person will be scanned and analyzed just the same. Privacy, at least as much as it is possible in email without the use of PGP encryption, is only somewhat guaranteed as long as you communicate with someone who either uses the same server or uses a server with similar levels of data privacy.

Cost is often a concern as well, though providers generally offer mailboxes from less than $10 USD per month. This may seem expensive compared to the cost of a small virtual server, especially if you have many users, but it’s worth taking into consideration the administration time in setup and maintenance, as well as the cost of any involved commercial software.

Potential Hurdles

It’s important to know what you’re getting into with running your own production email server. While you gain privacy and can reduce costs, you do have to do maintenance, even in a fully automatic system. In addition to normal system administration duties like security and bugfix updates, you’ll have to deal with diagnosing bounce notifications, adjusting mailbox quotas, and dealing with blacklists.

Blacklists are both a blessing and a curse for mail administrators. By validating incoming mail against them, you can reduce a lot of SPAM. However, you also must be careful to not end up on one through the actions of your users. A mail only server is not likely to run into this issue unless you have a compromised account or rogue user, but if you do web hosting on the same server you must make absolute sure that all web scripts are kept up to date. A server that hosts WordPress sites, for example, makes a poor choice to host email unless you are diligent about keeping your sites updated and secure.

Should I Run My Own Email Server?

If you aren’t comfortable with running your own server, don’t know how to fix email server issues, and can’t tolerate reception and delivery issues, running your own email server isn’t for you. In this case, I’d recommend checking out offerings from Google or Microsoft, or one of the many smaller providers.

It’s worth mentioning that you may still have the occasional reliability issue even with small providers. The presence of Google and Microsoft in this market is strong and they both tend to run the show. Other providers must constantly adapt to the standards they use and enforce.

Despite the warnings and pitfalls, there are some solid advantages to running your own mail server. Let’s explore the options.

Option 1 – Use Commercial Software Like cPanel

cPanel is a web hosting platform system that installs on RedHat Enterprise Linux or CentOS and reconfigures the system to provide a full array of services, including email. cPanel uses the Exim mail transfer agent (MTA) and has a very advanced configuration engine and spam detection system via SpamAssassin.

The amount of options available for customization via an easy-to-use graphical interface are numerous and can be overwhelming. However, the default configuration is very functional and will work for most users right out of the box. Users are offered a pre-package configuration of three webmail systems – Horde, Squirrelmail, and RoundCube. Also included is excellent support for the POP3, IMAP, and SMTP protocols, mobile support, calendar and contact sharing on iOS devices, and even full-text mailbox searching.

Licenses for virtual dedicated servers cost around $10 to $20 USD per month, depending on license vendor. It may come bundled with your server at no cost. You’ll also receive support from both your datacenter license provider and, as a last resort for more complex issues, cPanel.

Option 2 – Webmin / Virtualmin

Webmin provides an easy-to-install and configure solution for web and email hosting via a dual license plugin called Virtualmin. While similar in scope to cPanel, it doesn’t have as much user interface polish. That said, with simple configuration via a web interface, it is entirely useable and provides a significant shortcut to live production email.

Webmin/Virtualmin are aimed at a more advanced audience. While a novice could certainly install Webmin via the simple installer script provided, more command line and hands-on configuration is required over a system like cPanel. Webmin does provide far more customization options than cPanel, but this flexibility is generally provided via SSH commands and editing configuration files rather than via the graphical interface.

Webmin is open source and can be installed on a wide variety of Linux systems, including RedHat Enterprise Linux, CentOS, Debian, Ubuntu, and Arch. It also has an optional commercial license and support.

Option 3 – Rolling Your Own

cPanel and Webmin provide excellent default configurations, but these systems are resistant to extreme customization. Webmin tolerates this better than cPanel, but with either solution you’d be better off using the workflow and methods described in the documentation. Custom integrations with other systems may break cPanel or Webmin.

If you need something more custom, or prefer to avoid having a third-party software solution managing your email system, rolling your own is probably the best way to go. This isn’t difficult, but for scale installations it does require a bit of tool creation to ensure new users are added correctly, existing users are maintained, passwords are reset with secure values, and new virtual domains are routed correctly.

This option does require the most up-front work and knowledge. Building your own email server from scratch also requires more maintenance to ensure system updates don’t break your workflow and management system. That said, you’ll end up with a system that is truly your own and is configured in the precise manner you need.

Conclusion

If you are considering running your own mail server, I strongly recommend weighing the pros and cons before committing to the project. It’s a lot of work, both up-front and on an ongoing basis, but the benefits to privacy, security, and customization are hard to beat.
