dovecot - Jul 2013 - Difference between using auth_realms and setting up virtual mailboxes in postfix?

Hi, there is a possibility in the future that I might have to support
multiple domain names(but using the same IP address). Postfix has something
called 'virtual mailboxes' to help handle this.

But I also noticed that dovecot has a setting "auth_realms" where I
can
specify domains separated by a space.

What is the relationship between the two?

Hello Gab,

Let's suppose you have a simple Postfix/Dovecot server and two domains.

With Postfix, this is basically handled by telling it that emails for recipients
in those domains are to be delivered thru Dovecot's lda or lmtp.

On the Dovecot side, it is essentially a matter of having a mapping
address->mailbox, so that lda or lmtp know where/how to store emails.

Very distant...
Such realms may be used by some authentication mechanisms, and their names, even
if often looking like domain names, may be quite arbitrary.
