I have a mailhost with most of the domain users delivered locally and
some users (same domain) residing in other machines.
The relevant configuration:
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
local_recipient_maps = proxy:unix:passwd.byname, $alias_maps,
ldap:/etc/postfix/ldap-users.cf
transport_maps = hash:/etc/postfix/transport
/etc/postfix/transport:
foo...@example.com smtp:172.16.34.34
I don't want to create the users that reside in other host in the ldap
directory and, with this configuration, i get an "Unknown user..."
when i send an email to foo...@example.com
So, I extend the value of local_recipient_maps to include the desired
remote users with:
local_recipient_maps = proxy:unix:passwd.byname, $alias_maps,
ldap:/etc/postfix/ldap-users.cf, hash:/etc/postfix/to-transport
/etc/postfix/to-transport:
foo...@example.com x
Now, the transport_maps is evaluated and the mail is rerouted to 172.16.34.34.
However, is difficult to maintain /etc/postfix/to-transport because
there are quite users who needs this. A solution could be a catch-all
address but I read and advise from Viktor not recommending that.
I was playing with fallback_transport_maps but the user still needs to
be in local_recipient_maps.
Is there a better way to do this?
I read an old post (2000) from Wietse
(http://archives.neohapsis.com/archives/postfix/2000-01/0475.html)
talking about "re-vamping and unifying the virtual/transport maps" in
a similar thread and i was wondering how does it end.
