I have found a problem with SG. Some servers (such as Gmail) do not allow some kind of attachments (.exes, .zip with .exes inside).
If you try to send a message to a Gmail account with an .exe attachment, you get this message. (I did it from a yahoo address)

So, if you send a message to a SG account that poins to Gmail, nobody notices anything wrong, SG counter of redirected messages increases one, but the recipient never gets the message.
Is there a way of noticing the sender that his message didn't arrive without causing much trouble to the SG server?
