Oh, that's not my problem. I maintain the mailservers and am noticing
that some users (including me ;-) ) are recieving many virusmails from
some senders. Therefore, I wanted to block all mail coming from these
senders for (pop-)users of the mailservers. The senders all use their
ISP-smtp server, which I ofcourse can't block, because then all the mail
from that ISP is banned.
