..case in point:
fetchmail: 5.9.11 querying pop.net (protocol POP3) at \

..here is where I could have fetchmail say "DELE 1", "DELE 2" etc.
I only need the to auto-check _here_ for these viruses instead of 
doing it all in procmail _after_ wasting my own bandwidth.

..hints, ideas etc?  Use the Multidrop feature in fetchmail? 
"--tracepolls " ?

..in'man fetchmail', chk "Resource Limit Control Options", 
"SPAM FILTERING" and "SMTP/ESMTP ERROR HANDLING".  

..someone on this list mentioned some other program to check 
popservers before fetchmail'ing?
