Err - no - the answer is for the ISP to send the zombie victim one
message saying "clean your PC, then phone the help desk", then
disconnect them and block their login. If you put a barricade in
front of a zombie, the zombie owner will adapt around it (eg: program
the zombie to auto-create HTTP accounts for sending from, or
whatever). If you *remove* the zombie, well, that actually solves
That's quite expensive for ISP's to do, and gets them into the same sort of
ranting and whining that we see now from people who think SPF infringes
their freedom to send email from wherever they want pretending to be whoever
they want for their convenience.
