I have 3 MS Exchange 2003 SP2 servers each running on Windows 2003 SP2. They are all on the same private subnet. None are running firewall software.
One is new. Mailboxes on that server cannot successfully send mail to mailboxes on the other servers nor to any external mail receipients. The messages stay in the server's SMTP queue.
Those same mailboxes can receive messages without problem.
All servers can be seen and managed from the others.
Any thoughts on why messages are stuck in queue?
Attached are log files from both the new (sending) and old (receiving server). I'd appreciate any assistance.
