Hi all,

Our company are running redhat linux 8 and 9 with kolab( www.kolab.org ) mail server.
We have 4 mail servers across various branches.

I am looking for a mail server with more features and that are more robust than kolab.

It must do anti-virus scanning
Must scan for spam and remove it if from known spammers.
Must do content scanning and be able to release blocked content if so required.
Must auto replicate any users created and/or deleted at any time at any branch.
Must be able to create virtual email addresses ie aliasses for bulk messaging.
Fulle featured front end management system for operators to work but not manage it.
Anything that can do this and even more will help.

Any ideas...??

Thank you

kolab is not not a mailserver by nature, It is called a mailserver.

Basically kolab's internel mail server is postfix. If you want to built more robust, scalable mail server than go fo Qmail. Qmail mail can be configured with calmAV for antivirus solutions.
