NEWS: May 15, 2015 iRedMail-0.9.1 has been released, with Debian 8 and Ubuntu 15.04 support.

What iRedMail is

  • A ZERO COST, fully fledged, full-featured mail server solution. All used packages are free and open source, provided by the Linux/BSD distribution venders you trust.
  • An open source project, released under GPLv2, hosted on BitBucket.

IMPORTANT NOTE: We have only one edition of iRedMail, it's free and open source. All mail services related features are implemented in iRedMail. When we talk about "Pro", we're talking about iRedAdmin-Pro (web admin panel for iRedMail). You can add unlimited accounts with either iRedAdmin-Pro or other tools like SQL/LDAP command line tools or web applications like phpLDAPadmin/phpMyAdmin/phpPgAdmin.

What iRedMail does

  • Install and configure mail server related BINARY packages automatically from the official software repositories provided by Linux/BSD distribution venders.

Note: on FreeBSD, packages are installed with ports tree.


  • Works on main stream Linux/BSD distributions. No matter you switch to which Linux/BSD distribution listed below, you can get the same mail server in few minutes.
CentOS CentOS CentOS CentOS CentOS CentOS
  • Full-featured web admin panel - iRedAdmin-Pro. Online demo is available, purchase here. You can setup mail server manually with the same softwares as used in iRedMail, but you cannot find better web-based admin panel than our iRedAdmin-Pro.
  • Zero cost, fully fledged and full-featured.
  • Fast deployment in LESS THAN 1 MINUTE, easy to use and stable. View YouTube Video to check how easy it is.
  • Your mail server setup is reproducible.
  • Control over your own data. You have all personal data on your hard disk, it is not on somebody else's storage medium.
  • All components are free and open source softwares, and you get the bug fixes and updates of the used packages from the Linux/BSD distribution venders you trust, not iRedMail project.
  • Works on both non-virtualized and virtualized boxes, e.g. VMware, Xen, KVM, OpenVZ, VirtualBox, with i386 and x86_64/amd64 support.

Why not outsource the email service to external entities

Quote from Spamhaus news article:

However, outsourcing (the mail service) does not come without costs, even when the outsourced service appears to be "free". Hidden costs include:

  • Another organization can see the content of all messages. In some cases, the contents of messages are stored on the outsourcing company's servers indefinitely. External access to unencrypted emails poses privacy and confidentiality issues. Furthermore, the outsourcing company may be located in another country and be subjected to different regulations and obligations.
  • In some cases, the outsourcing company's terms and conditions allow it to search the content of emails to aid in targeting advertising, which poses even greater privacy and confidentiality problems.
  • The organization no longer has control of its own email security. Server-based encryption and authentication is managed by the outsourcing company, requiring end-to-end encryption for sensitive communications.
  • Large companies with many customers are often a target of cybercrime attacks aimed at stealing customer data, and some of these attacks have succeeded.
  • Inspection of SMTP transaction logs may be impossible for the end user. Troubleshooting failed deliveries and other email problems requires interacting with an external support desk. Support desks are sometimes slow to respond. First-line support, in particular, might lack the training and access to fix any but simple problems, requiring escalation and further delays.
  • Sharing a mail server with other organizations can cause delivery issues when a user at another organization sends spam through that mail server. When the outsourcing company fails to detect and block spam, or is slow to terminate service to spammers, the likelihood of problems increases substantially.

I have worked with Unix/Linux mail systems for nearly two decades and it has always been a struggle dealing with large numbers of domains and virtual users on a single server. I looked long and hard and actually ran several solutions on small servers for many months before making the decision to purchase iRedAdmin Pro. The product paid for itself in the first couple of weeks in time saved alone. What sealed the deal was the excellent level of technical support that I received when we had a glitch. The problem was resolved quickly and the whole event was completely transparent to our users. iRedAdmin Pro is a mature product with great support and ongoing development. I could not give it a higher recommendation.

Thank you so much for all of the great work you have put into the iRedMail system!

It (iRedMail) was so easy to install and start using I thought something was wrong. After extensive testing, found it is a reliable, secure, and the best part - a "small footprint" system. I like the iRedAdmin interface so much I didn't hesitate to upgrade to Pro, and highly recommend it when I am asked.

How has my support experience from the iRedMail team been? Exceptional!!!! Kind and most important - friendly and respectful. I had a few questions I sent, thought it would be a day or 2 before an answer back, and it was quick!

My overall experience is so good I am recommending all of my clients to at least use the open source version and upgrade to the Pro, and not even waste their time using any other system.

We are running iRedMail with iRedAdmin-Pro for almost a year now. There have been a lot of updates and improvements. Whenever you need another function which could be useful to a lot of people just tell and in the next update you have it. The support is very quick and good. Thanks a lot for this wonderful program.

iRedMail is the our choice, thank's to the use of standard packeges and solutions for e-mail management. Before we used sendmail and we was searching for a system that implemented maildir + Dovecot upon LDAP for the managemet of user accounts, so iRedMail is perfect for us. Moreover it is free, has a very good support - and I emphasize *very good* - and the Admin Panel - iRedAdmin-Pro, we bought as soon as deployed iRedMail, is a very valid tool to manage the system.

iRedMail is the easiest and reliable mail server with all of the features that a mail server needed for the administrators.I appreciate the developers of iRedMail who have really supported tremendously to deploy the mail server by solving all of the problem of us quickly. 3 cheers to iRedMail.
