Interesting. I have not seen this but given that end-user access is likely
to increase in bandwidth, this is perhaps going to increase. Sigh. I
suppose the only action left is for ISPs to block / filter outgoing SMTP at
the IP level.

But when you have lists of 30 million email addresses, is this feasible?
The reason I ask is that it apepars to me - after looking at mailq - that
these are sometimes just auto-generated alpha email addresses. The
particular case I spotted was AOL. If you add 30 million duff  email
addresses, I fear the only impact will be on the unsuspecting relays... but
maybe not?
