Whooa!
I'm backing up! My hack actually seems to work! ;-)
In case anyone googles this thread: this seems to work for me. Happy to
hear feedback from others.
I put this as one of the entries in my nnmail-split-fancy variable. It's
a bit crude as it doesn't assert that the string is actually a MIME tag
and not just part of the text in the message, but I'll live with the
risk ... ;-)
(: (lambda nil
(save-excursion
(save-restriction
(widen)
(goto-char (point-min))
(when (re-search-forward
;; The regexp "\\s-+" means "one or more whitespace chars".
"^Content-Type:\\s-+text/calendar"
nil
t)
"calendar") ))))
Cheers,
/Liman
