At the end of september,2001 unknown spammer, that lives near VERIO
backbone sends more than 10 millions messages to unferyfied e-mails,
and (oh, no...) he use e-mail from our domain in mail from: and From:;
as result we got about 2 million errors from MTA's around the world.
Solution was simple - adding more RAM to servers, limitting numbers of
incoming connections from one host, also we are set hard bounce for
that user. That's all.
