[Mimedefang] Detecting and adding headers if attachment found.

[Bryan Martin]

A lame newbie questions but here we go.

My intentions are to have procmailrc copy any message which has an
attachment to a certain directory but I need to have mimedefang add a header
to label it as such.  This way I can see what files are being blocked and if
any adjustments need to be made.

I come from a windows background so I attempted to add a "global variable"
to the top of the "mimedefang-filter" located in "/etc/mail".  With that I
had plans to make the global variable on/off to indicate whether or not
mimedefang found an attachment.  I added this at the top "$invalidAttachment
= "No";"  which to me indicates a global variable being defined with "No" as
the default value. Next inside the "filter" sub inside the "if
(filter_bad_filename($entity)) {" block I added "$invalidAttachment =
"Yes";" to indicate that an attachment has been found.  Later inside the
"filter_end" I added a statement like this:

 # BM 4/28/04 - Attempt to check for attachments
         if (my($invalidAttachment) eq "Yes"){
                action_add_header("X-Attachment-Removed",
"$invalidAttachment");
                add_recipient($AdminAddress);
        }else{
                action_add_header("X-Attachment-Removed",
"$invalidAttachment");
        }

However, the message always comes in with "X-Attachment-Removed" equaling
nothing.  Can someone help me out?
