One of our clients is running exchange 2003. We have been having some problems where every now and then we get listed on spam blacklists. This is causing problems with sending email.
In short, I would like to setup a connector so that mail is sent via my isps mail server, can someone help?
I tried to set it up once, following the instructions here:
But then, every message I tried to send I would get an ndr with this error:
"A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients."
