GWIA or DNS problem?: 450 Host Down error on outgoing mail

Asked by ttheimer in Novell Groupwise

Tags: host, 450, down, gwia

I have a GroupWise server that is receiving mail properly but attempts to send produce the following error in the GWIA log (addressee is a mailbox at TTPSpecialProjects.com):

    DMN: MSG 1721 Send Failure: 450 Host down (TTPSpecialProjects.com)

- I have verified the BdrMgr filter exceptions against the Novell TID10013822
- I can initiate a telnet session from outside into Post 25
- I can initiate a telnet session from the GW server to port 25 on an outside server.
- I can use a domain name for the outgoing telnet session so the dns appears to be resolving.
- Contents of route.cfg: myorg.com [192.168.10.91]  
   (where "myorg" is the org's domain and the IP is the GW server internal IP)
- Contents of resolve.cfg:
                   domain myorg.com
                   nameserver 12.127.17.83
                   nameserver 12.127.16.83

System is NW6/GW6.5.  GW, BdrMgr, DNS/DHCP all run on one file server.

I am looking for ideas on the possible cause and tests I can run to rule out possible causes.
