I have a client that has a SBS 2003 Server running Exchange. They have a static IP with AT&T. The IP keeps getting blacklisted and we are unabel to send email to certain domians. I have configured a smarthost on the Exchange server to try and relsove this, but we continue to get blacklisted. I have scanned every PC on the network and the server and they come back clean. I have had it with this thing!
Has anyone successfully used the the dyndns mailhop relay program to get by this issues? Will this product enable our Exchange server to be able to send and receive email to anyone even though our IP keeps getting blacklisted?
I really need some help on this one. I need to get this resolved ASAP!
