I'm doing some research about mail server software, because I want to migrate my mail server to Linux.
I've found some good solutions like,
· SuSE Linux Openexchange Server
These are just a few I found. All got almost the same functions (wide range of supported clients, ...)
If someone has some experience with it, can u tell me what the best solution is for an organization around 200 employees. I thought maybe SuSE Linux Openexchange Server because the main distro we use is SuSE, but it is little bit costly I think. Around $1,400.00.
We needed a mail server for our organisation, and i was given the job of administering it
I had a look at sendmail, qmail, etc, etc, and concluded that i dont like these C mail servers with their horrible horrible configuration/installation.
Someone recomended Apache James to me. At first i thought it would be a bit dodgy using a java mail server. But i went with it simply because configuration was ridiculusly simple, and have stuck with it ever since!
We've got about 50 accounts running on it, and it works a treat - never crashed. Ok, so it's never had to deal with huge volumes of mail, but i get about 200mails a day.
Only downside i've found is that it doesnt include stable support for IMAP.
I still recommend the toaster I posted. It's not that hard. I set it up with Zero knowledge of Mail Servers. Granted it took three times, but for any half knowledgeable person it should be easy. It does take time but then again you end up knowing how it all works. and it's %100 percent free with lots of forums supporting it. I know first hand of at least two companies that are using this set up with over 40,000 accounts. They advertise hundreds of thousands of not only accounts but of virtual domains. Again it's not an easy one button set up, but once it's up and running you'll be glad. Oh and did I mention $0. hahaah
Go for qmail, I have been using it for a couple of years and it is the best, pretty easy to install and rock solid, I am also using squirrelmail, it is kept very up to date and has alot of good plugins that are very easy to install.
I suggest you http://www.postfix.org
pretty much like sendmail but much more simple....
pop and smtp server configuration very easy... should give it a try, good integration Amavis+Antivirus+spamassassin (virus + spam)
I'm setting up our new mail server and that's what i'm using...
postfix+clamav(anti virus)+spamassassin+amavis(antivirus+spam/server interface)
I too suggest Postfix. I started out with qmail and ended up using postfix. It has less to configure. If you are going to use a web-based email client, I suggest using imp over squirrelmail. You have the option of adding other things to it (address book, calendar, etc) from Horde.
