Hello,
We have an office in the UK and when I send an email to them we get teh follwing error
"#< #5.4.4 X-Postfix; Host or domain name not found. Name service error for name=THE UK DOMAIN type=A: Host not found> #SMTP#.
The strange thing is we can send just fine from outside our network. Why is this happening and how can I resolve this issue. We are using Exchange 2010.
