Hmm. Rejecting viruses at SMTP time instead of accepting them and then
bouncing them does have this wrinkle.
Remote senders of viruses aren't a problem, since their messages
will have come through their MTA, which can generate a sensible
rejection message.
I take it you are therefore interested in your local users getting a
meaningful message when they attempt to send a virus ?
I control my client machines and most of them are unix, so although
I had discovered this problem, I haven't bothered to address it yet.
Now you have got me wondering.
A user might send a document contaminated with a word macro virus,
but these days most viruses propagate by sending themselves, so it
isn't the user's MUA, but the virus' MUA that counts.
When a virus sends an email, would the user see the "mail failed"
message ?
