qmail vs... exim??
I'm strongly considering moving our shared hosting servers away from sendmail - sendmail lumps all email together in 1 file (mbox format) - so when a customer accesses his pop/imap account with 100mb of email, the server has to open a 100mb file. This causes unneeded stress on the server and performance issues to the end user.
That being said, I'm now considering alternate MTAs which use maildir format - the 2 options that I know about are qmail and exim.
From what I see, CPANEL and DIRECT ADMIN both use exim. I've heard that qmail is fast, efficient and secure.
My question is, what is the difference between the 2 (performance, flexibility etc..?)
Thanks
