(Sorry for the late reply, I've been a bit on the busy side this week, and wasn't
keeping up with a few lists)

Will all those who are using Barracuda gear to do anti-spam filtering please
check if their boxes are still set up to generate outbound bounce messages
when they detect spam?  Remember that if you get a spam with a forged/broken
source address, the bounce message is *itself* spam...

Here's a web page about this issue:

And how to fix it:

(I can't find a reference, but I seem to recall that earlier software versions
for the Barracuda didn't support these settings, so you may need to upgrade the
software before doing this....)
