what is wrong with this regular expression in procmail recipe?
In order to sort mailing list postings, I have to add several processing
rules for every list, like:
Trying to put it up in one single rule, I end up with the following 3
line which unfortunaley do not work correctly.
Idea is to sort all mails with any of these headers (To, TO, CC, Cc)
into "gunpg-users" mailing list.
Any idea what is wrong with that reqular expression?
