I assume that the rejection refers to a message coming from
"82-69-6-203.dsl.in-addr.zen.co.uk" which is valid but contains the
dirty word "dsl". I have seen a few servers complain about that sort of
thing. They assume dsl means residential and/or too small to run a mail
server, which around here certainly isn't the case. The simplest
solution is to change your ptr record.
