A couple of days ago our district stopped receiving email from anyone outside our network.  I can send within and outside, I can send from within our groupwise emails but we cannot receive from outside sources.  I have tried emailing myself from my other email accounts outside but nothing.  I have gone through our PIX and Gateway but nothing has changed.  At the GW server I have been having issues with the GW Internet Agent which continues to close.  I used to restart it and it would be good for a few days (had to also restart the PO Agent and Web Agent) then it got to the point where only a server restart would do the trick and now it is not working with any means so far.  On my Log this is a cut and paste of the typical error I keept receiving:

Can't help you with the Groupwise stuff, but I would be glad to take a look at your PIX config to see if I can find anything there that could be the culprit...

i pretty sure its groupwise, like cause and effect. Like i added the %&^%$$ files from Novell in to the correct dir and subs. then no outside email. I guess i will have to go back find the files i added and replace them with old one, which of course i don't have backed up. But I do have a couple other mail servers set up the same way..

Ok lets go.. Had to take a walk...
I am running netware/ grpwise  6.5 all the 'stuff' gwia, poa,webacc, mta is running on the same server, with one nic. as far as the mx I am part of the county of lake, they hold the mx records. I have the server behind sonicwall. I runs in its own "DMZ" I am not too sure about resolver.. thats the DNS? I figure the is public record. Inside we have a world of routers, with heavy state security. So we have a division of labor.
This one's kicking me though...
Can you send out but not receive in, or is it outbound that fails but inbound's OK, or no internet comm at all?

The particular error eptexascrazy posted is an outbound error, not an inbound error.  However, have you examined your GWIA message folders for the offending message(s) to find who they're from or to?

If GWIA is not configured to send response messages with a FROM: of Postmaster, or if Mailer-Daemon isn't set us as an alias for Postmaster, GWIA can get into a message loop if someone sends something from the outside to Mailer-Daemon and it's not deliverable.  That's one thing to check.  See TID# 10056642 in the Novell KB for more info on that.

If you don't have a ROUTE.CFG configured, since you're most-likely behind a NAT firewall, it's also possible you're not able to route a message from GWIA to an internal address, potentially also causing a message loop.  If I remember right (it's been a while) you'd put the host name that the MX record points to in the route.cfg, but your server's private IP address.  That way, internal messages to would go to the GWIA directly instead of out and then back in.

Another possibility is that somewhere in your county's public network setup you've got an "intelligent mail host" like a spam filter or a store-and-forward mail host, rather than your GWIA going directly to the Internet.  In such case, your GWIA config should be using the "/mh" (mail host) switch, to point outgoing mail to the mail relay.  If that mail host is a) unreachable or b) they changed the name or c) the /MH is otherwise wrong, you'll get a 450 host down on outbound messages too.  Make sure if the mailhost option is set, it's pointing at a valid, reachable mail host, and the host name is resolvable by the server.

That's the other part of the picture - make sure whatever mail server address is failing is reachable and resolveable.  If it's not in DNS but you know the host name and IP address, adding it to your server's SYS:/etc/hosts might fix it...
Sorry for your efforts… This is what happened: I panicked.
I have a dozen servers. I had forgotten that I had move a new server into a DMZ to handle the internet stuff.
I applied a patch for problems I was having with Backup Exec on my post office server.
I then restarted the server. No gwia. So I started the gwia. Now, unknown to myself  I have two running! The one which should be running gwia started abending, 'course since I forgot about it, I never looked at it..
After reading shineons suggestions, I started to realize that my problem was more connection orientated. Since I could telnet inside the building to port 25 but not outside
When I got to work today, (more calm) I looked at firewall configuration and and saw I had the internet traffic pointing to another server! I could have hit myself in the head! I suddenly remembered setting up the server to handle internet traffic and placing it in a DMZ!
So I turned off the gwia running on the post office server. Restarted the gwia on the DMZ server, and now all is well in Social Services. Lesson learned. And I thank you for the calming influence.
Forced accept.
