Hello. I'm trying to set up an email server several days. I think the most difficult part is to know when what does what. I wish to be clear on some concepts.
I am running cyrus + postfix + ldap on a gentoo server, multiple virtual domains (sealed mail server, no mail user have system account). It seems to me:
1. Moden mail servers don't often do mail forwarding. So upon receiving an email, it will always be 'local delievery'.;
2. Documents often mention 'delivery agent' and 'maildir', it seems 'delivery agent' is not a standalone package, there is a delievery agent in postfix package, and there is also one in cyrus package, I can choose to use the delivery agent (postfix's or cyrus')
3. maildir is a way to store email, it is where postfix save incoming mail, and it is the place cyrus-imapd get emails so that to put to user's INBOX. But an email server can have no maildir completely, and let cyrus's delivery agent by pass maildir and put mail directly to user's INBOX.
4. putting the incoming emails in to each coorisponding domain's email storage place is the job of delivery agent.
I feel messed up reading all the documents, now I am afraid I got severl concepts completely wrong so I just write what I think plainly and hope someone kindly come out and say to me "hey, you got xxx wrong here", and I'll be thankful:)
Thank you. --- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
