Are any of you aware of a POP email server which does authentication with account info stored in mysql ?

Hi Alex,

Your best choice is to use Courier-IMAP with the vpopmail authentication module.

What MTA are you using? It will depend on whether your mail is stored in mbox or maildir format. Most POP servers will only read one or the other. For maildir format Vpopmail works very nicely with Qmail's POP server as well as Courier-IMAP. Tpop3d is one that I've run across that will handle both mbox and maildir format. I've never used it, so I can't say how good it is. You can find it here:
