How many of you guys run your own email servers? What distro/packages do you use? I'm using qmail at the moment with 30 domains and about 200 users.
We use different MTA depending on the OS. Our servers have exim, qmail, mailenable installed. The number of email accounts & domains depend on the user's requirement.
We use Zimbra 8 (open source edition) for our mail. Zimbra is based on postfix and gets the job done quite well for us. We hacked it to support CentOS 6. Our email failover cluster allows our backup mail exchangers to hold emails until another mail exchanger is available. This ensures that no email are ever lost in a service maintenance or outage.
In my own 10+ years of experience we have used nothing but FreeBSD for email eventually. The specific reason being emails are very IO intensive and require good IO response with low overhead. While Linux has come a long way yet BSD is great for frequent read/write as it is with emails and disk recovery actually works pretty well. Choose UFS2 though ZFS is fine as well. This is my own recommendation. Internet may say otherwise but I have never googled. I have used mostly all flavors of distros and filesystems including the old school journalfs if BSD is way out for you and linux is familiar, go for ubuntu LTS server as you will get most help and tools here. As for applications the standard packages with any distro are generally fine. We tried a couple in the few years and finally came down to dovecot for IMAP/mailboxes. Roundcube for webmail. lastly choosing MTA is personal preference. It can be postfix or exim whichever you are most comfortable with. We chose postfix because at the time exim just wouldn't work on BSD but its default on debian based systems I believe. hth
I've used postfix on Debian and Ubuntu before but like the way that Qmail runs although we are having a small problem with simscan at the moment. I may have a look at Postfix on BSD..
I have a mail server on a single server (Debian 7), i use raiserfs on SSD disks and never has problem of I/O
I'm running MailEnable on Windows 2008. It's ok for now but looking into possibly upgrading to a better solution that allows us to monitor the emails more closely as part of our company is sales which focuses a lot on emailing.
I have own mail Server using Postfix + Dovecot + Spamassassin + Amavisd + Postgrey + Clamd + Razor + Horde ..
We run our own mail servers and use Postfix as MTA and Dovecot for the IMAP folders. In addition we use Z-Push for PUSH mail delivery to mobile devices. If you're looking to setup your own mail server, I can recommend a script called iRedMail for a start, although a manual setup is alway better, given you have the experience.
