It's not being dropped based on the filename since those will notify the
recipient along with an admin mailbox.

Recent debugging shows that it may be something strange with how the
email is being generated.  We can't get the originator of the email to give
us the details of how it's being created.  It seems that the problem is with
some automated generation process but when they just create the email
using Outlook and attach the PDF, it seems to work fine to all recipients.

However, there may be something with how MailScanner (or a Perl library)
is processing the email attachment because even when the email was
being generated with an automated process, some of the recipients
received the PDF fine if they didn't go through MailScanner.

The email size seems to stay the full size all the way through multiple
email servers including MailScanner but when we "view source" on the
client, it's chopped off short.  I guess this could be a mail client issue
not being able to interpret the MIME encoding if something was a
little off.
