email not getting through

[jdt at acn]

Does any one have any idea about this problem i am having with my exchange
server. Last week our server stopped working with the smart host. when i
change to using dns most emails go through but some is not getting through
even though we were responding to the email and so know the email address is
correct.

any suggestions welcome thanks
