Iris

Iris is a totally free and open-source web-based software that packs a lot into one project. It includes a CGI script, Dovecot configuration files, an Exim MTA (Mail Transfer Agent), along with Ansible and Vagrant playbooks. Pretty cool, right?

Build Your Own Email Server

Thanks to its foundation on technologies like Exim, Roundcube, Dovecot, SpamAssassin, MySQL, ClamAV, and Perl, Iris lets you set up your own email server. You can enjoy features like authenticated SMTP relay and virtual domains. Plus, it makes managing vacations and accounts super easy!

OS-Independent Fun

The best part? Iris is OS-independent! So whether you're using Linux or something else, as long as you have a modern GNU/Linux distribution installed, you’re good to go. It also works great with popular web browsers like Mozilla Firefox, Google Chrome, Opera, Internet Explorer, or Safari.

Key Features of Iris

This software has some neat features that really stand out:

• Handle multiple independent domains with separate aliases and users.


• A web-based interface in PHP for managing accounts.


• Stop malware before it gets to your inbox by rejecting mails based on real-time anti-spam or antivirus software.

Integrated Monitoring & Auto-Responders

Iris also keeps an eye on your quota through integrated monitoring tools. And if you're going away? No worries! The vacation auto-responders let you inform people about your absence using the Roundcube webmail software's vacation add-on.

User Privileges Made Simple

You’ll find two types of users in Iris: those with privileges and super-users. Super-users can change anything they want while regular users can only modify their assigned domains based on their quotas—keeping things organized!
