Unlikely - qmail may throw stuff at a stupid rate, but it doesn't throw
away things that get a 4xx on connect. Sounds very much like fully
fledged spamware.

It appears to be Lyris (judging from the SMTP banner on that server) - I
find it hard to believe that Lyris is that broken. Sounds like a good
case for greylisting (with a 24 hour expiry period).
