rejecting the message should alert the user that something is wrong.
Most MUAs will say "hey! they didn't take my mail!" and only outlook
won't tell you why.
5xx Message rejected because of infection with Worm.YouSuck.Loser
Well, rejecting a message does alert the user if the user is sitting behind
their mail client that sent it. Most viruses have their own engines to
send out copies of itself. While the 5xx response message is still sent
back it never makes it to the person using the computer to make them
aware of the rejection.
Out of curiousity, has anyone (recently) experienced a situation where a
real user was attempting to send out an email with an attachment that
contained a virus? I can't say that I have. In any case, I'm quite
certain that 99.999% of all virus email on the net today is generated by
existing viruses and not legit users who accidently attach a virus.
