Thanks, Mark.

Having sent my test email with pdf attached I thought all was fine, but an
email from a club with pdf was auto discarded this morning :-(

My pass_mime_types is now:


Looking at the header of the  message discarded I see:

MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="===============12345678=="

Do I need to add
to pass_mime_types or something?
