We are wasting allot space to this subject.
I agree with this too.
Something like this in ~/.procmailrc should help:
:0: * ^Subject: Re: Suggestion for Newbies \[Was: Curt Tone\] * ^X-BeenThere: fedora-list\@redhat.com /dev/null
(Not sure about the backslash escapes.)
The first line (":0:") designates the beginning of a "recipe". The lines starting with asterisks are patterns to match in the header. The last line is the mailbox to deliver to. (In this case, the message is discarded to the bit bucket.)
For a more useful example, here's my recipes for the Fedora lists:
:0 : * ^List-Id:.*fedora-announce mail/Lists/Fedora/announce
:0 : * ^List-Id:.*fedora-devel mail/Lists/Fedora/dev
:0 : * ^List-Id:.*fedora-list mail/Lists/Fedora/users
These deliver to Dovecot IMAP folders in ~/mail/Lists/Fedora.
