I do it all the time (perhaps twice a week). No problems so far.

This only shows that you still have much to learn about spam :-)

Filtering for an open list with roughly 600 subscribers is far more
difficult than filtering for one person, since the breadth of topics
and styles for non-spam is significantly higher. This is a real
challenge for statistical filters.

I think that, given the constraints, Debian list spam filters aren't
bad.

  "The Debian Listmasters do their best to stop as many such
   emails as possible from reaching the lists. On a typical day,
   over 40,000 such messages are blocked." [1]

A couple of times I had the "honor". Dunno whether it was a bad
sysadmin or barracuda itself. Not a nice souvenir, mind you.

See above. If you go to the below reference, you even get to
propose SpamAssassin rules to the Debian list masters. I'm
sure they can use some help. They're volunteers, after all.

Saying they have "zero interest" (even if they not only do the
heavy lifting of filtering out 40K spams /a day/, but also document
what they are doing, for your and my reading convenience, all at
no cost, on a volunteer basis) is offensive.

Repeat with me:
 - you don't bounce spam at all, because you're bouncing to
   the wrong address anyway, thus just enhancing the problem.

   (There is still a reason to bounce a (legitimate) mail,
   but NEVER-EVER when you think it's spam).

 - you don't reject to mailing lists: they'll conclude that
   you have delivery problems and unsubscribe you.

This is common consensus, and for a reason. If your provider isn't
doing that, they ain't pros and are just pissing in our common well.

Sorry for being so clear, but I feel strongly about mail: it's the last
means of communication left where I have the choice of client software,
the other stuff being "antisocial networks", where some random web
designer gets to decide what I see and how. I hope I die before this
dystopia is upon us (I'm old, mind you).
