[Mailman-Users] Custom handler applied to digest to filter excessive quoted text?

[John Williams]

Hi all,

Is it possible to create a custom handler for digests only? 

I want a mail list that automatically strips out duplicated quoted text in digests, so the same quoted text doesn't appear over and over. Such a thing doesn't appear to exist in any mailing list software, so I'm looking for the second-best thing, which is currently software that easily allows such a filter to be inserted.

Any other ways people handle this problem, aside from telling users to not quote excessively?

Thanks
