I have a postfix setup that, for a long time, has done exactly what I want.
But now I have to change something and I have no idea how to make this
particular change:
E-mail from several domains are sourced on my network. Now I need to treat
e-mail with the From: line
u...@domain1.com
differently from e-mail with the From: line
otheru...@domain2.com
Until now, both those From: lines have been treated the same -- some
processing, then mostly sent to a relayhost, with some specific destinations
handled via the transport map; but now I need to send all e-mails with the
second From: line to a different relayhost from the one that handles the first
From: line.
There are two features that support sender-dependent routing:
sender_dependent_relayhost_maps
This looks up a relayhost value that depends on sender.
Like relayhost, this uses default_transport.
It is seached with the envelope sender address and @domain.
sender_dependent_default_transport_maps
This overrides transport and destination.
It is seached with the envelope sender address and @domain.
In most cases, sender_dependent_relayhost_maps will do the job.
In a (failed) attempt to get this working, I have added the following to
main.cf:
sender_dependent_relayhost_maps=hash:/etc/postfix/relayhost_maps
I have created the following /etc/postfix/relayhost_maps file:
----
@arrl.net [smtp.pobox.com]:587
----
I have done the usual
postmap /etc/postfix/relayhost_maps
and
postfix reload
but when I try to send an e-mail from my address n...@arrl.net it is still not
routed to smtp.pobox.com, but to the server designated on the normal
relayhost= line in the main.cf file.
Please, what am I doing wrong? The documentation seems pretty sparse in this
area, but my interpretation of what I can find is that the changes I have made
should work.
Thank you for your patience.
