Linux Distro for mail server

[madman045]

Currently have a client who is looking to change mail server packages

Currently running vpop3 on 2003 server, but the performance isnt great and it hammers the server with antispam turned on

So we are looking for a lightweight linux distro to start with, for just email, AV and antispam / webmail

Whatever we decide in the end, it will need to initially support 100 users

Currently have the following pc to test with

Duron 750mhz
192mb
20GB
CDROM

Can anyone recommend a distro and the associated packages

Ideally with a gui as im a complete linux n00b

Thanks

Thanks Andrew,

I will give Cent OS a go and grab the packages you mentioned.

Three AVs, do they all integrate with it then?

I've used Clam AV before.

I looked at clark connect, but they dont really want to spend anything hence they havent bought exchange server.

I think it will be running more on a high end pc then a server.
