=> Seen that too. Seems that the spammers do not rely on DNS for sending
their crap (it makes sense : DNS MX lookups can take some time and delay massive
mailing) and have a kind of domain <--> mailserver database.

=> How about just use another IP for this server and make sure the old IP is no
longer used.
