Is that other ('rogue') server serving the zone as a master or a slave? If
it's a slave, and it was getting zone transfers from your name server(s),
then it should eventually expire the zone data and everything will go away
(except for stupid name servers, like AOhelL's, that ignore TTLs and hold
stale data in their caches for weeks and months on end). If it's a master,
then it will continue serving the bad data until you can get its admin to
remove the zone from it. On the other hand, if it's a slave, you could
always re-establish the zone on your master server, but give it MX records
that point off into oblivion. Then, the next time the secondary grabs a
zone transfer, everyone will be going off into the void.
