I've been looking at this a loooong time tonight. Despite my best
efforts, I did not find a reason for the duplicate email.
I even created my own content filter to rule out some kind of
spamassassin/spamc/spamd miconfiguration. I'm still receiving emails
twice with this customs content filter turned on (only once with the
content filter turned ooff).
I turned on verbose for cleanup and trivial-rewrite but there was so
much output and much of it repetitive that it didn't help me determine
what's going on.

Hopefully something jumps out at you.
Isn't this as simple as:
1. new email comes in, is delivered to content filter, with bcc to
always_bcc recipient.
2. content filter re-injects email into the queue for final delivery,
postfix performs final delivery, with bcc to the always_bcc recipient?
Since these are 2 separate deliveries (with different routes) as far as
postfix is concerned,there will be 2 messages to the always_bcc
receipient, and no deduplication.
Kind regards,
Tom
