[Mimedefang] Skipping scan on Forwarded mail - "Forward as Attachment"

[Mathew Thomas]

Hi,

mail gateways running Solaris 9 with Sendmail 8-13.1 +Mimedefang 2.44 +
SpamAssassin 2.64 with Uvscan & ClamAv

Some of our staff received W32/MyWife.d at MM  virus which were sent to
them as forwarded mail as Attachment.

 If the virus is not part of the forwarded mail attachment, the system
is picking up the viruses.  Will mimedefang scan forwarded mail which is
sent as attachment? How deep it will scan? 

Thanks
Mathew
