days. I have read some of the follow-ups to this post. But I
haven't yet seen the simplest, to my knowledge, way of catching an
empty or blank or just-angle-brackets header. This is it:
:0: # brackets contain caret, space, tab, angles
* ! ^From:.*[^ <>]
/dev/null
Good. It also will catch the absence of any From: header at all, which
something like
:0 # brackets enclose space, tab, both angle brackets
* ^From:[ <>]*$
/dev/null
would miss.
It doesn't need the local lock, though.
