Outgoing mail stuck in queue with response of "the remote server did not respond to a connection attempt" to any domain (Exch2k3)
Posted on 2004-10-25
I'm currently running an Exchage Server 2003 w/ SP1 on a Win2K3 box. I have no problems receiving email (pennnetworkconsulting.com is the domain). However, I cannot send any outgoing mail regardless of the domain. I have tried a large amount of domains for email tests and none go through. All of these domains can be resolved fine (via nslookup) from the Exchange box, but they sit in the outgoing queue on retry with a "the remote server did not respond to a connection attempt" message. Forcing the connection does not help. I've done a dnsreport.com test on my domain without any errors. The Exchange box sits behind a Netgear WGT624v2 router with all the appropriate ports being forwarded. I can telnet into my exchange server from the outside world fine (used a remote terminal server). I've been searching through other similar questions, but none have helped. It does not appear to be a DNS issue--I'm running DNS on the exchange box with it pointed to itself for resolution and have my ISP's DNS servers as forwarders. I completly re-worked my entire setup over the weekend in hopes to resolve the issue--but alas, no dice. Any ideas are greatly appreciated, I'm at the end of my rope here. I have a feeling that it's something simple and I just need another pair of eyes to look at it. Thanks!
