Hi List,
I have read the documentation, and do not understand if this is possible,
but I think it should be. I have a spam filter that is required to listen
on the MX of my domain, but it does not support alias expansion, so the
postfix server has to do the expansion then send the message back to the
filter for final delivery.
That is a fairly standard: either one expands aliases before or
after a content filter.
Is it possible to deliver virtual mailbox maps to the mda, but relay
virtual alias maps back to the filter?
Postfix receives all mail from the filter, therefore expand your
virtual aliases in Postfix and be done with it. No need to filter
mail twice.

This solution requires delegating alias buckets to someone, rather than
everyone, which does not meet the enduser requirements. The issue is a
conflict between the enduser requirments and the filter requirements, it
appears that I will not be able to satisfy one of them.
Thanks for the help.
