Hi all,
I’m having some issues figuring out if this is possible and then if so, how to
approach it. This isn’t for production use, just some internal testing and
experimentation...
My goal is to set a relay destination based on the SASL username used for smtp
authentication. So if I have users “testsmtp1”, “testsmtp2”, “testsmtp3”, I’d
like to select the relay destination based on that username, NOT on the
envelope From.
I do have this version of it working, which does use the envelope From.
In main.cf:
# enable sasl auth
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
smtpd_sasl_authenticated_header = yes
# map of sender to transport
sender_dependent_relayhost_maps = hash:/usr/local/etc/postfix/relay_by_sender
In the "relay_by_sender” map file:
testsmtp1 qmqprelay1
testsmtp2 qmqprelay2
testsmtp3 qmqprelay3
And in master.cf, the custom transports:
qmqprelay1 unix - n n - - pipe size=250000
user=qmqp argv=/usr/local/adm/bin/sendqmqp.pl 10.9.8.200:631 ${sender}
${recipient}
qmqprelay2 unix - n n - - pipe size=250000
user=qmqp argv=/usr/local/adm/bin/sendqmqp.pl 10.9.8.200:632 ${sender}
${recipient}
qmqprelay3 unix - n n - - pipe size=250000
user=qmqp argv=/usr/local/adm/bin/sendqmqp.pl 10.99.8.200:633 ${sender}
${recipient}
In the above configuration, when I connect to relay using any of those
accounts, there is no match and the default transport is used.
If I add an entry to match the From address, that works fine, as expected.
So can I do this, but use the SASL username?
Thanks,
Charles
