CANNOT RECEIVE EMAIL FROM OUTSIDE - EXCHANGE 2010
Posted on 2012-08-21
I have an issue where the exchage is has stopped receiving emails from outside.
I run SBS 2011, and the server was working fine but suddenly the exchage stopped receiving emails from outside.
When I send emails from outside, the emails are getting sent through but my users are not receving those emails in thier INBOX.
The emails are not bouncing back to if they been sent from outside.
When i send emails form Inside to External domains , it goes through fine. Also if we send email between the local mail accounts internally it works fine.
When I tried to telnet into the Exchage server from command prompt, it comes up with the "421 4.3.2 Service not available" Connection to host lost.
Please advice me urgently as , i have to get the exchage working back.
