Linux Internal Mail Server
 

Dear Linuxians,

I have to set a new mail system for my old postoffice internal mail system. Linux mail system that i have in mind is sendmail and zimbra but need some additional information on other internal linux mail system so that to make a comparison on advantage to be taken from.

Could you please suggest me a linux internal mail system for server.

Other options to sendmail include postfix, exim, qmail

You don't really say what you're trying to achieve so it's difficult to give advice. Zimbra is a complete Collaboration Suite and comes in a free Open Source version and a paid-for Network Edition with additional features - both versions have an Ajax web client for viewing mail. The recommendation for Zimbra is to install it on a dedicated server. it's extremely simple to install and requires very little configuration.

On the other hand, sendmail and similar products are MTAs and aren't the easiest products to install/configure. Depending on your requirements you'll need additional software.

Zimbra is complete and easy to setup. (uses Posfix, Spamassassin, ClamAV, etc in the backend)
Zimbra on CentOS how-to

Open-Xchange is another option

Roll your own using Postfix, Cyrus IMAP/POP, etc..
Virtual users with Postfix MySQL on CentOS
virtual users and domains postfix courier mysql centos

Thanks
 

Dear Linuxians,

Thanks for your quick reply on this post. I was not aware of mentioned software such as exim and X-echange. However it seems that some products testing is needed.

my postfix server has been up for 5 years.. only being shut down once when we moved offices.. It's a LOT more stable than MS Exchange imho.


Comcast the Cable ISP is switching it's users to Zimbra.. is that enough testing ?

Not sure what you want.. do a bit of searching you will find HUGE universities that are using distributed postfix installations for thousands of users.

Hi farslayer,

Thanks for your advice. On my side i'm searching an internal mail not a mail to send message from outside as we have already in the company MDeamon software. However it's my old postoffice on NT4 which must be replaced by another system which will be his equivalent on linux.
