dear all, i have 2 servers that were *given* to me to setup and implement webmail solution for our client. i have done some groundwork in terms of the backend applications that are needed to do this.
This doesn't have much to do with PHP. In fact it can probably be done without PHP.
The ideal setup depends on your situation. How many domans? How many users? How much email?
If you have multiple domains, I suggest you look at
http://inter7.com/freesoftware/
They have a complete package to manage multiple virtual domains on a Qmail server using only one system user. I've been using it for a couple years, with good luck. There is an active development effort
If I was going to setup two machines as mail servers, I would put half the users on each, with all the programs running on both. Then I would setup MX records so that each server backed up the other, collecting email for later delivery if the other server is down. This way if one of the machines goes down, half your users still get mail, and the messages for the other half are queued on the remaining server.
Be sure to keep a backup copy of one machine's configuration on the other. You should have everything you need to re-build a dead server on the other machine. If you put the user mailboxes and mail queue on separate hard drives you can pop that drive from one machine to another very quickly.
You can run Apache on the mail server to manage email accounts, and for webmail, but keep all non-mail related web services off of it. You don't want all the web developers logging on to the mail server.
