Exchange 400 4.4.7 Message delayed
Posted on 2014-12-16
I have a problem with Exchange servers after I moved to a new hosting place.
I have 2 AD's on seperate networks.
Domain1 with Exchange 2013
Domain2 with Exchange 2010
If I try to send an email from Domain1 to an email adress on Domain2, I get the following error after a couple of hours:
Remote Server at domain2.tld (IP.IP.IP.IP) returned '400 4.4.7 Message delayed'
16-12-2014 11:34:43 - Remote Server at domain2.tld (IP.IP.IP.IP) returned '441 4.4.1 Error encountered while communicating with primary target IP address: "Failed to connect. Winsock error code: 10060, Win32 error code: 10060." Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts. The last endpoint attempted was IP.IP.IP.IP:25'
I cant figure out what the problem is... Anyone have an idea ??? Thanks....
