Thanks so much for the thorough explanation; I did not realize the
software checked Mime parts. Great info; problem solved.

I am not sure why it is finding an "asc" file as only a PDF was
attached.
The banned files mechanism checks mime parts, not only attachments.
Furthermore, even if I added ".asc" to the list above, it is still
flagging the email as having banned content.
A text-file attachment internally transforms to a list of strings:
["multipart/mixed","application/octet-stream",".asc","file.txt"]
Your default policy has to handle those mime-types appropriately.
Example of a PDF inside a zip archive:
["multipart/mixed","application/octet-stream",".zip","file.zip",".pdf","file.pdf"]
A plain text body of a mail without attachments:
["text/plain",".asc"]
Your case probably has been:
["multipart/mixed","text/plain",".asc"]

IF PROMPTED, AND VERIFY THE EMAIL ADDRESS MATCHES THE SENDER. CONTACT
