This is not a productive direction to pursue. The feature you're
looking for is not there, and is not planned. You need to find
a different solution.
If Quanah is asking for the sender login map to automagically
expand Postfix virtual alias maps, then don't count on that to
ever happen.
Not really, no.
My point is there are three queries necessary to deliver this email.
Postfix does two of them, and gets all of the data it needs via those two
queries to do the third and final query, and thus deliver the email. I
understand it is the prerogative of the postfix team to not further expand
the queries, so that's that. If there was a way to use an lmdb table to
rewrite the request for the domain prior to the LDAP lookup, that'd be
another way to solve the issue.
