Bad idea. It's tough enough on the host running a list with 1500 or
2000 people on it. Adding outbound filtering for each user would
be a real burden on the list host. It's better to distribute the
processing by making the user agent (or mail transport that's delivering
to the user) do the filtering.
In addition, a filtering majordomo will only 'protect' the lists that it
serves. I don't know about you but I get a lot of spam from all sorts
of different sources. I need to have a filter anyhow. It's not hard to
add some more rules to filter out each lists's bozos. It's a lot
simpler to do that than it would be to upload filter rules to each
of the 10 or 12 listservers I get mail from.
There's also a security issue. How are you going to set it up so
that I can't say hack Tim May's filters to send him nothing but posts
from Phil H-B and Detwiler? Yea, you can do it with passwords or
PGP or whatever, but it's still more overhead. Why bother with it
when you don't need to?
