The answer is still no formal support.
The only way to get true virtual domain support
is via multiple IP addresses and a jail system.
This is just one step below running physically
different servers.
So unless you have /27 network handy to handle
just your email domains (you'll acutally probably
need a /26 which is 63 usable IPs as one goes
to the router), you're looking at some kind of
naming system where you either invent some unique
three or four letter code to append to each email
name like userddom or you do some kind of pattern
substitution like user_domain_dom as the login name.
I guess you could get away with non-standard ports
to give each domain its own unique port but that's
not very scalable.
The answer for the hoobyist is as follows:
- name map [EMAIL PROTECTED] to user_domain_dom
whenever you create an address.
- Using some kind of email name rewriting method
(MTA dependent), change all incoming addresses
from [EMAIL PROTECTED] to user_domain_dom.
- Have all users of the system login
as user_domain_dom. Once they set up their
user name once they rarely need to type it
again because the MUA usually saves this info.
- You can point mail.domain.dom to the same IP
for all domains.
If you wanted to use the partitions in Cyrus
to physically separate the domains mail store
you can do this (but you will still need globally
unique mailbox names).
Happy Hacking!
