I am in the process of building an email server for about 4000 users.

I have used contribs.org's SME server for several sites - but there is a bug in RedHat 7.3 that doesn't allow more than 2057 users.

So - I opted for a pre-installed version of RedHat AS 4 from Dell with the hardware I ordered.

I had hoped that - since going closed source - RedHat had made great strides in the ease of administration of their server class systems.

It seems I was wrong.....

I don't see much (or any) improvement since RH9 - maybe I'm looking in the wrong place.

I have my RHCE - but this server needs to be administered by normal admin type people - I'm hoping there is something better than webmin for administration.

I'd consider a commercial product - if the price were right.

Any thoughts - feedback welcome.

After downloading and running the free 30 day AS - I may scrub the hardware when it arrives and go with something else.

Which mail server are you planing to use? Qmail?
