Greetings,
I would like to reroute mail for all our recipients if a certain
header
is present.
Eg. Mail to 'm...@mydomain.org' has the header 'SomeHeader'. I would
like
to reroute this email to 'm...@some-server.mydomain.org'.
What is the best way to accomplish this in postfix?
thanks,
Ryan
See http://www.postfix.org/header_checks.5.html and look for the
REDIRECT action. Use it with a header_checks rule something like:
/^X-MyHeader: foo/ REDIRECT u...@example.com

Thanks for the response Noel. It looks like REDIRECT only works with a
specific destination. I would like it to work for all users. Eg.
m...@mydomain.org, header 'MyHeader' ---> m...@foo.mydomain.org
y...@mydomain.org, header 'MyHeader' ---> y...@foo.mydomain.org
u...@mydomain.org, header 'MyHeader' ---> u...@foo.mydomain.org
Does an entry in header_checks need to be defined for each recipient? If
so, it wouldn't be feasible due to the number of addresses we have.
Is there another way to accomplish this?
regards,
Ryan
The header_checks REDIRECT action works as described in the man page,
ie. it examines one header and will redirect to a single recipient.
If that doesn't suit your needs, please describe in detail the problem
you are trying to solve, maybe there is a solution.
I'm not sure what other details you need. The exact problem is listed
above. But some background:
Cisco Unity allows users to receive their voicemail through email (as
.wav attachment). This email contains the header
'X-CiscoUnity-MessageType'. They can also forward their voicemail to
another user through email by sending it to
'someotheru...@unityserver.mydomain.org'.
Redirecting via header_checks does not appear to be possible
in this case. Header_checks does not know the recipient(s) of
the message.
But this entails that a user remember the unityserver domain. We'd like
the process to be cleaner by allowing forwards to their public address.
Then our smtp will be responsible for rerouting it to the unity server.
Hope this helps.
Would redirecting all mail addressed to
u...@unityserver.example.com => u...@example.com
be a reasonable solution? If so, the details of how to do
that might depend on how example.com is currently defined and
delivered in postfix.
I still get the impression we don't have enough details of how
mail is handled at your site and how the unity server
integrates into it to provide a robust solution.
