It is currently 3.1 running Apache-ssl with Frontpage extensions. Seems like that could be overkill for a web server, unless you're relying heavily on server side includes or doing moderate to serious database work. >We have about 150 virtual domains running on the web server and about 800 >dialin accounts + the mail from all the virtual domains running off of that >one mail server.

Why is this a problem? It's perfectly normal for FreeBSD to use swap, even when the machine is under a light load. I've seen mail servers with a load average > 10 using more swap than you have RAM and they're just fine. Remember, it's a only a mail server. I don't think that speed is something to be terribly concerned about. >I have read up on doing round robin DNS with the Web Servers, but never >really understood how the disks are synched up, does it run on NFS with one >machine serving the content? > >How about scaling the mail servers? Where can I read up on setting up >multiple mail/pop3 servers? What is the best solution to do this. Why? Again, your machines are doing just fine. Save your money for additional phone lines/bandwidth/advertising/etc... You really don't need a HW upgrade at this point.
