Picking an Email server

[djones]

We currently use MSExchange for our email server. I would like to shift to a Linux server. My first linux server. What Linux compatible email server is recommended for small applications (< 50 users)? Also, will the normal Outlook client programs interact with the Linux version of exchange so that I do not have to change the client side?

hello,
i personally like redhat for my mail server, i have it set up for POP3 access, but it only serves my home network. it can do movemail, imap... i am not sure what ms exchange uses..

I used to work at a joint with an exchange server. They have a proprietary protocol to talk to the clients, but it also does do IMAP. POP3 and the usual. Lookout and Lookout Express can both be reconfigured for a POP or IMAP server

[pbharris]

Red Hat is a type of linux.

There are numerous email server software for linux. Sendmail, postfix, etc. I've heard some very good things about postfix.

Are you going to be needing other features of exchange (eg, calandering, etc...)?

[/quote]Yes. It would be good to get a direct replacement for the Exchange product, but I am willing to make sacrifices. I am running Exchange 5.5, and need to upgrade to the current version, Server 2003 and then the numerous Virus, firewall, etc....payout...so I am looking for an alternative. I have about 20 clients, but should plan for 50 users.

Since this subject is somewhat complex I'd recommend either:

A) Buying a good book on the subject.
B) Searching for a good tutorial.
C) Hire someone to do the work for you. I'm available. *wink wink*
