Hello. I'm trying to set up an email server several days. I think the |
5 |
most difficult part is to know when what does what. I wish to be clear |
6 |
on some concepts. |
7 |
|
8 |
I am running cyrus + postfix + ldap, multiple virtual domains (sealed |
9 |
mail server, no mail user have system account). It seems to me: |
10 |
|
11 |
1. Moden mail servers don't often do mail forwarding. So upon receiving |
12 |
an email, it will always be 'local delievery'.; |
13 |
2. Documents often mention 'delivery agent' and 'maildir', it seems |
14 |
'delivery agent' is not a standalone package, there is a delievery agent |
15 |
in postfix package, and there is also one in cyrus package, I can choose |
16 |
to use the delivery agent (postfix's or cyrus') |
17 |
3. maildir is a way to store email, it is where postfix save incoming |
18 |
mail, and it is the place cyrus-imapd get emails so that to put to |
19 |
user's INBOX. But an email server can have no maildir completely, and |
20 |
let cyrus's delivery agent by pass maildir and put mail directly to |
21 |
user's INBOX. |
22 |
4. putting the incoming emails in to each coorisponding domain's email |
23 |
storage place is the job of delivery agent. |
24 |
|
25 |
I feel messed up reading all the documents, now I am afraid I got severl |
26 |
concepts completely wrong so I just write what I think plainly and hope |
27 |
someone kindly come out and say to me "hey, you got xxx wrong here", and |
28 |
I'll be thankful:) |
