Hrrm.  That's multi-line.  Try "[^\n :]+:".  Or maybe "[^\n :]+ *:",
which is wrong by rfc822 but wouldn't surprise me anyway.

Just be sure you are not too restrictive.  It's better to split some
letters that contain "From " in the body than concatenate two letters.
If the first letter is long and uninteresting, the user won't even see
the second.  For example, you are sure the buffer has never been
narrowed to contain the "From " line but not the following header line?
