I'm having an issue with a SBS2003 with exchange 2003. I've set up a new web domain name which we are going to use within the recipient policy. They already have several domain names so nothing new but, with the new domain name I'm getting a bounch back saying the connection is refused. This is coming from the external ISP "4.4.0 - Other network problem '[Errno 61] Connection refused'". Now this domain name isn't setup any different to the other domain names but this is only happening with the new domain name.
I am running Sophos PM and I have set that up as the others as well. The only thing different to this domain name to the others is a different DNS host but I can ping and telnet to the address and get the same response as the other domains.
I just don't know what else to do and they are trying to roll out the rebranding with the new domain name and this is holding them back now.
