I tested it with:
== transport
example.net smtp:[127.0.0.1]:26
== sender_canonical_X
r...@example.net ad...@example.net
== master.cf
127.0.0.1:26 inet n - y - - smtpd
-o smtp_generic_maps=hash:/etc/postfix/sender_canonical_X
Result is an endless loop until I get "554 Error: too many hops", btw. the
sender-address wasn't rewriten
After this I've changed the master.cf to:
cleanupX unix n - n - 0 cleanup
-o sender_canonical_maps=hash:/etc/postfix/sender_canonical_X
-o transport_maps=
127.0.0.1:26 inet n - y - - smtpd
-o cleanup_service_name=cleanupX
-o transport_maps=
Now the sender-adress is rewritten, but the email is stil send in a loop..
I guess that the "transport_maps" option doesn't make any difference because it
is part of the qmgr. This would be an explantion for the loop, because after
the rewrite the email is saved in the incoming folder. Which is later processed
using the values of the transport_maps configured in main.cf.
I've already tried to configure an own qmgr by setting an new queue_directory.
The problem is, that the socket files are still created in the directory of the
default qmgr, but on runntime searched in the new queue driectory (file not
found errors in maillog).
Any suggestions how I could solve the loop or force that the socketfiles are
written in the new queue directory?
