Thanks Andreas. And you're probably right that I need to dive into fancy
splitting. But sticking with the simple approach for a while -- and
taking your suggestion -- suppose I have a header block containing the
following: 

From: Andreas Schwab <schwab@linux-m68k.org>
Subject: Re: nnimap-split-methods syntax
Newsgroups: gmane.emacs.gnus.general
To: Tommy Kelly <tommy.kelly@verilab.com>

Any ideas why doesn't it match on this:

("andreas-etc_to_me" "^From:.*linux-m68k.org\\(.\\|\n\\)*To:.*tommy.kelly@verilab.com")

thanks,
Tommy

P.S. I'am aware -- given your explanation concerning the action of ^ --
that it could also match in the obscure case where the "To: ..."
sequence wasn't anchored at the start of a line (e.g. if it was in a
Subject). But still, I don't see why I don't get a match despite that.
