Bounce filtering is a delicate problem because we don't want to
damage the reliability of email.
Aim is to only delete worms, leave other bounces intact.
AFAICT extra.dat installation muct be manual :-(
ClamAV is free and has a good reputation for email filtering.
Need to record the Received: chain of infected messages before deletion.
At the moment we lose information if the message went through a relay.
