I don't see any "Return-Path: <MAILER-DAEMON>" in our quarantined

Amavisd always places the Return-Path line at the top of a quarantined
message. Are you seeing the "Return-Path: <MAILER-DAEMON>" as the
first line, or somewhere later down in a quarantined message?
Btw, what type of quarantining do you use (one file per message,
one mbox file for all quarantined messages, sql, ...)?

If it is indeed the first line, I suggest to find the corresponding log entry
made by postfix to see what the MTA got as a sender address.

Amavisd does not turn a null sender address into a "MAILER-DAEMON".

The only exception is when quarantining to a unix mbox file
(one file for all quarantined messages), where the mbox separator
line would look like "From MAILER-DAEMON ...timestamp..." for a
null sender address, but this does not affect the Return-Path line.
