Here is an odd error – I have a client who cannot send or receive email to/from another domain. My client’s side gets no error message when the messages are sent,as thought the message went through, the recipient never gets the message and when they try to send a message to my client they get an error that “No transport provider was available for delivery to this recipient”
I am able to send and receive from my office to either person but they can not send to each other – their ISP’s are the same company. My client runs an Exchange server and the other side is hosted by the ISP – any thoughts on the black hole that exists between the two companies?
