An outbound e-mail (with forbidden attachments) was filtered out by GWava 3.7 (which sits on the MTA), so the e-mail never reached the GWIA and because of this (as far as I understand the process inside GW) is shown in the users mailbox as unsent (what in fact is true).

Is there an intelligent way to resolve this besides from deleting the e-mail?

Thanks in advance.
