My Server has SBS 2003
My Server has SBS 2003 installed on it, which is running Exchange 2007. Whenever users on the network try to send emails to a private source they just go into a queue and never leave. But if the same user tries to send on to @yahoo, @msn, @gmail etc. it is fine and goes straight through.
I have looked into it and I am not on any sort of blacklist. The mails for the companies that won´t send have been sent many times before with no issues so I know they don´t have a problem. I tried it with my own personal domain and that won´t work either.
The internet works great and I can access the websites of the people I am trying to email. I need help with this any advice would be appreciated.
