Problem sending Internet E-mail Messages
Posted on 2008-06-25
I'm having problems sending Internet e-mail messages on a new e-mail server (exchange 2007). I'm getting the following error across all domains: 451 4.4.0 Primary target IP address responded with "421 4.2.1 Unable to connect." Attempted failover to alternate host, but that did not succeed. Either there are no alternate hosts or delivery failed to all alternate hosts."
This is a copy of the send log

I'm fairly new to Exchange 2007 and could use some guidance on this issue.
