Jaro Mail :: The Electronic Postman

Jaro Mail is an integrated suite of interoperable tools to manage e-mail communication in a private and efficient way, without relying too much on on-line services, in fact encouraging users to store their email locally.

Rather than reinventing the wheel, Jaro Mail reuses existing free and open source tools working since more than 10 years (and likely to exist for longer) and is mainly targeted to Apple/OSX and GNU/Linux desktop usage.


    • Minimalistic  interface with automatic threading
    • Targets intensive usage of mailinglists

This software product was tested thoroughly and was found absolutely clean; therefore, it can be installed with no concern by any computer user.

  • Does whitelisting and integrates addressbooks
  • Can do search and backup by expressions
  • Automatically generates filtering rules
  • Computes and shows statistics on mail traffic
  • Secure password storage (native OS keyring)
  • Provides advanced maildir management tools
  • Stores e-mails locally in a reliable format
  • Defers connections for off-line operations
  • Checks SSL server certificates (imap, smtp)
  • Supports strong encryption messaging (GnuPG)
  • Is multi platform: GNU/Linux/BSD, Apple/OSX
  • Old school, used by its author for the past 10 years


To use Jaro Mail on your desktop client, you will require some programs. These programs are ready into the Apple/OSX package, but you will have to install them by yourself if you use GNU/Linux, preferably using your favourite package manager.

It is recommended that you read the user manual: this is not exactly a typical consumer grade software and you won’t get far unless you know what you are doing. Even for experienced Mutt users there are things to learn in the manual, on how Jaro Mail redesigns the e-mail workflow for instance.

Download Zone Jaro Mail is made available in a ready to install form for Apple/OSX desktops. GNU/Linux users should  install all required programs and compile the sourcecode until distribution maintainers will make this software into a package.

More interesting software

If you are concerned about your privacy, or in need to keep your communication confidential, then we recommend you to encrypt your emails using the GNU Pretty Good Privacy tools and ask your peers to do the same. On Apple/OSX JaroMail includes its own version of GnuPG which won’t conflict with other installed versions, however keep in mind that if you need military grade security you are better off using GNU/Linux.
Those looking for a powerful text editor can also have a look at our pre-configured distribution of Emacs called AutOrg which can well integrate with JaroMail.

Uniquely available for GNU/Linux users is our other software Tomb, the crypto undertaker a small program to create encrypted folders promoting techniques that are well secure like key/storage separation, steganography etc.

Tomb also integrates very well with Jaro Mail, for instance one can make the ~/Mail and ~/.gnupg directories reside into a tomb which will mount them in place inside the $HOME via its bind-hooks.

Other interesting e-mail frameworks

Jaro Mail is not the only thing out there that makes you handle e-mails in a geeky and smart way, in fact there are plenty of projects like this out there and the real difficulty is to find one that is usable and most likely to endure years of development and still work with old setups.

Why all this text based stuff?! there is a wonderful world behind every Terminal ;^) for an introduction have a look at the Flossmanuals CLI guide

Below you will find a list of frameworks that can be used as an alternative or complementary to Jaro Mail, since we all use the maildir format to store emails:

  • mu stands for maildir utils: it might be harder to install for the novice hacker and has less user-friendly documentation, but it definitely looks like a solid and fast alternative to our setup, using some different and less mature internal components.
  • cone is a COnsole Newsreader And Emailer that brought some innovation into the console email world and some of its users are very happy with it
  • notmuch is made by a Debian developer and is what most Debian people are happy about, see notmuchmail.org

“The aptly named JaroMail is a step in the right direction – precisely how I’ve used email the last 10 yrs” – Julian Oliver

There is much more as well there are some different internal components which we might support as optional in this framework, it all depends how much is the need and demand for more features. If you know of some other projects that should be listed here please do not hesitate to contact the dyne.org hackers.

What about the name

Besides being a mispronunciation of the nickname of its first user (Jaro Mail is spelled exactly like Jaromil while chewing bubblegum, it was hilariously suggested as a name for this software by our friend Max Kazemzadeh) it is also interesting to note that the nickname Jaro is used to familiarly indicate a friend in some dialects spoken on the eastern coast of the Adriatic sea, especially by people living in Bosnia and some southern parts of Dalmatia (coastal part of Croatia).
