LSoft's Listserv product does this as well - subscription confirmation messages
and some other administrivia mail are sent with MAIL FROM:<> so forged
subscribe requests don't generate bounces. The upshot is that if you block <>
your users will never be able to subscribe to any Listserv-hosted list.
There's enough sites running Listserv that it might be a bit more impact than
"I can't e-mail SORBS"...

I have always been amazed at how products like the Barracuda or the PIX can
ship with totally broken software, and yet get enough market share to cause so
much pain for the rest of us.  Some days, I wonder if there's grounds for legal
action - do such broken "training wheels for net admins" products constitute an
attractive nuisance? ;)
