Hello All;
I currently have the following setup in my main.cf:
alias_maps = dbm:/etc/postfix/aliases, nis:mail.aliases
I've also enabled myself to receive email for about 15 domains.
Everything works just fine, but because of some new domains I am now charged
with maintaining, I am now faced with how I am going to synchronize these new
domains users into my aliases, preferably in a way that would require very
little effort on my part.
What I am looking for is a way to forward all email for say domain XXX.COM to
host server-1, if a users account is not found locally in either my aliases dbm
or my NIS maps, ditto for domain ZZZ.com to smtp host server-2. Some of the
users for XXX.COM might be residing at my domain/environment, therefore I need
to first lookup locally before forwarding. Finally, the next stop on this
forwarding would be Microsoft AD/bridgehead servers, just in case that matters.
use a shared map that contains all users and for each user contains the
host where email should go. you can either use virtual_alias_maps:
[EMAIL PROTECTED] [EMAIL PROTECTED]
if the final host doesn't like the rewritten address, you can use
smtp_generic_maps to rewrite it back (this happens after transports, so
doesn't break the virtual alias functionality).
or you can use transports:
[EMAIL PROTECTED] relay:[host10]
if you use transports, you need to pre-process the file to remove the
transport on the host itself (where the transport is obviously local:
and not relay:[host10]).
