I found one more interesting tidbit: I looked in the source mailbox (main.mbx) file for one of our client's mailboxes. When the attachment is successfully visible, it shows up in the mailbox file as:
------=_NextPart_000_01D2_01C3AF71.46A21B20 Content-Type: application/pdf; name="MC11-19-.PDF" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="MC11-19-.PDF" However, when it is invisble, then attachment starts as: ------_=_NextPart_000_01C3B427.3A499190 Content-Type: application/ms-tnef Content-Transfer-Encoding: base64 I wonder if this could be something that Declude Spam is doing? I hope there are more of you out there working today and willing to help.
