how to mail instead of post a followup

One of the mailing list groups I'm reading on gmane.org doesn't allow
posts via gmane. So, posts and follow-ups need to be e-mailed.  I ran
into this many years ago, and vaguely remember adding some sort of
article hook that check the group and did something to cause a posting
to be mailed to the appropriate address instead of posted.  (Modify
the followup-to: header line?).  But, I can't find any trace of my
previous solution, and google hasn't turned up anything either.

Does anybody else remember how I solved this problem?  :)
