Nope, I'm not misstaken. An infected mail is not rejected while my smtp
server is receiving the mail, it turn of the connection with an ok. No
bounce at this time. And then it sends an bounce to the sender with
virus warning message.

Maybe there should be an idea to change the behavior of qmail-scanner so
it reject the mail instead of accepting it. But then where can not be so
much details in the virus report because the sending smtp do not know
anything about the virus.

I'm not trying to solve a problem that dosen't exist. I'm just trying to
make sure that there will not be any problems.
