When the virus attempt is sent repeatedly, it does chew server resources to be 
detected.  clamav has to run "on it" after all.

My goal is to to detect the sender IP, and block those repeat-send-receive-scan 
loads.

That's the current problem.  It's a DISCARD, not a REJECT.  There's no REJECT 
message with IP.  Just the discard notice without it.

Obviously the IP address is, at some point in the transaction, correlated to 
that message.  Need to figure out how to preserve & get at that info.

messages are connected.

Saw that too.  Haven't figure out yet how to make sure it gets ONLY the right, 
correlated 'other line'.  The procID match sounds good - not sure yet if or how 
you can do that.

the following:

Adding a header with the IP could be an option.  I think I'd have to have 
Amavis add that header WHEN it detects/discards the virus, get that passed back 
to the Postfix log, and then have f2b detect it there.
