Virtual Mail Server on CentOS 5
I've been working with Linux for servers for about 4 years, but have never really had to set up a mail server before. I am now tasked with this, and despite my own efforts, I can't really seem to get anything working.
I'm using CentOS 5, and the mail server needs to do POP/IMAP as well as SMTP, and needs to support multiple domains. Evidently this is a really tricky thing to set up.
Can anyone recommend software to do this and the simplest way to get it all up and working? All the guides I've seen look to be hugely overcomplicated, and I'm wondering if it really is quite that complex...
Any feedback or help would be great.
