Hi Viktor,
TL;DR fixed, case closed.

Anecdotal reporting is useless. Only "postconf -n" output is
believed here. If you have a multi-instance Postfix environment,
check the correct instance. If mail traverses multiple instances,
make sure each is configured correctly.
My apologies, I should have included that.

The postfix docs say that postfix first tries patrick+foo@... and
then patrick@...
The documentation does not lie. However you're doing "recipient
verification" and the message is in fact rejected by the nexthop
MTA (which likely does not support address extensions).
That made me dig into more logfiles and you were totally right. The
nexthop was rejecting it. I thought Postfix was rejecting it.
but I don't see two queries in the openldap logs.
Just one query for patrick+foo@... and that email address does not
exist in openldap. Why is there no 2nd query for patrick@...?
What am I missing?
http://www.postfix.org/postconf.5.html#propagate_unmatched_extensions
propagate_unmatched_extensions = canonical
With this setting together with a tweak in the ldap setup it now works.
or configure the nexthop MTA to support address extensions.
It's an LMTP client and it does not support that so I'm happy that
Postfix offers a solution :)
Thank you for pointing me in the right direction. Most appreciated.
Regards,
Patrick
