OK, this will fail on messages with no Content-Transfer headers, which
I have seen lots of messages with such mess.
No, not at all. This recipe does not even look at the message headers.
Here is a sample I tested.
Spam Message:
[deleted except for relevant body part]
------=_NextPart_000_00E3_01B14A3A.E0116B77
Content-Type: text/html;
charset="iso-8859-1"
Content-Transfer-Encoding: base64

Here is the log.
procmail: No match on
"^Content-Type:(.*\<)?text/.*^Content-Transfer-Encoding:(.*\<)?base64"
Of course I can understand why this happened in this message, since
you were looking for the header.
Well, no, your interpretation of the log isn't correct, because
the recipe is not looking at the header at all.
The recipe failed because the "charset=" line got in the way of a
match. I had assumed it would be wrapped, but that was a false
assumption. Only continuation *header* lines are wrapped; not
logically continuing lines in the body. Change the condition to
this, and it should work:
* B ?? ^Content-Type:(.*\<)?text/.*(^.*)?\
^Content-Transfer-Encoding:(.*\<)?base64
In fact, it does work; I just tested it on your message fragment.
