I did not come up with anything. You have the first filter:
smtp inet n - n - - smtpd
-o content_filter=filter
snfilter unix - n n - 10 pipe
flags=q user=filter argv=/var/spool/filter/filter -f ${sender} ${recipient}
which sends everything through the pickup daemon. I could not find a
way for 'pickup' to differentiate mail from <root> (for example) from all the
other mail.
You mentioned you are changing the filter to deliver via smtp. I'm
sure this will be more flexible.
I don't know what this filter does, but moving it to the amavisd-new
reinjection port might be an option. Then you would need to override
the content_filter for the pickup daemon to prevent loops. Downside is
since recipient expansion occurs within amavisd-new, unless I'm wrong,
the filter would be called for each recipient. On the other hand, does
this filter expand the recipients so amavisd-new gets a separate
message for each recipient? If so, you should consider placing the
less efficient filter in front of the more efficient filter (if it
makes sense to do so). I assume when a message is expanded in
amavisd-new, the reinjection port gets one separate message for each
recipient.
