The current options you can select with clamd when a virus-infected email is discovered is to either silently delete it, or deliver it to a "virus" folder. Other mail systems I have worked with would outright reject the email and it would be returned to the sender. I find this method to be a lot nicer than either silently deleting it or delivering it to a "virus" folder as:
- When deleting it, neither the sender or receiver are aware that the message contained a virus. Matter of fact, the receiver has no idea that a message has even been sent to them, and the sender has no idea that the receiver didn't get it
- When delivering it, the sender still has no idea that the message contained a virus, and the receiver now has a virus-laden email message on her computer.
So, in short, I would like to see the ability to reject/bounce the message back to the sender as well.
