[Mailman-Users] Subject Line Munging

[Roy Rapoport]

Looks like my lists are correctl prepending a TAG to the subject
line when configured to do so.

But it looks like when people respond to email, mailman doesn't
bother to filter out the old occurances of the TAG.  So in other
words:

Someone sends an email to the list titled 'foo'.
List gets subject 'TAG foo'
Someone responds with 'Re: TAG foo'
List gets 'TAG Re: TAG foo'

etc.

Is this correct behavior? Am I missing a config switch or something?
