Occassionally a user's email password will become compromised and the spammer will flood the Qmail queue with 10,000+ emails sent through a specific user's account. I know how to use qmqtool to remove messages that match a specific string:

qmqtool -d -f "[email protected]"

However the -f argument matches anywhere in the message.

-f 'STRING' display comma separated list of message number(s) containing STRING.

That means messages to, from, and even mentioning that email address will all be deleted. Does qmqtool (or another qmail tool) have a command for matching messages from a specific envelope sender?

Note: I only want to match the authenticated sender, not the "From:" which is always forged in this case anyway.
