Thank you, Noel!
I got that running - mostly :)
Server A (MX, SMTP: smtp.example.com) has:
relay_domains = $myhostname, localhost.$mydomain, localhost,
/etc/postfix/mydomains
relay_transport = smtp:[smtp.example.com]
mynetworks = [ip.ad.dr.es], ...
Where /etc/postfix/mydomains lists all domains to be relayed and the
relay_transport is the IP of Server B:
Server B (IMAP, imap.example.com) has:
relayhost = [smtp.example.com]
mydestination = $myhostname, localhost.$mydomain, localhost,
/etc/postfix/mydomains
mynetworks = [ip.ad.dr.es], ...
This setup works for me - beside one problem:
The /etc/aliases of Server A will not be honored, which means that all
mail to any of the domains will be transported to Server B, which in
turn will bounce the mail.
Right. /etc/aliases is expanded during local(8) delivery. If
you must expand aliases on the gateway, use virtual_alias_maps
(not! virtual_alias_domains)
But it's generally better to pass the original recipient to
the internal mail server and do the expansion there.
I would like to let already Server A bounce those mails!
Using a relay_recipient_maps as you wrote, seems to be the right way,
but i cannot get it running.
Like in a /etc/aliases file, i want to accept certain users for all
domains.
I tried to create the file as follows:
awk -F: '{print $1}' /etc/aliases | egrep -v "^(#|$)" | awk '{print $1"@
OK"}' | sort -u > relay_recipient_map
So, for example, it contains lines like:
user1@ OK
user2@ OK
But this does not work :-(
relay_recipient_maps must list the u...@domain.
us...@domain1 OK
us...@domain2 OK
us...@domain3 OK
...
I would not like to list all users for all domains, but just accept mail
to the existing users for ALL domains (as shown in my example above).
List them all individually. Don't worry about the size of the
file; it won't affect performance.
