You have two problems.
What is the overall message type in the main message headers? I suspect
it was not multipart/mixed or multipart/alternative; possibly
multipart/related or some such which would cause all of its sub-parts
to be skipped because multipart/whatever is not accepted.
Further, even if the main message is multipart/mixed, you don't accept
the message/rfc822 part so the only thing left would be the initial
0.2K text/plain part.
You need to accept every multipart/ type that could possibly contain a
sub-part of interest. A better choice for pass_mime_types is
In your example above, this would pass all the multipart types
regardless of sub-type as well as the message/rfc822 part. This
doesn't mean the entire message will be passed. It just means that the
various sub-parts of those parts will be examined and the text/plain
Even though the above seems very liberal, it ultimately only accepts
text/plain and elemental message/rfc822 parts, in this case only the
two text/plain parts.
