Sorry for the long note. Any help would be appreciated.
I have a Domino 8.0.2 server running on Win2003 server. There are times when the server will stop communicating with other email servers. The problem has to do with the inability of the Domino server to resolve the MX record of the other email server. Not sure why this happnens in the first place, but I was told several things like slow bandwidth could cause this to happen. Anyways, when the Domino server fails to get the MX record, the server will revert to the domain's "A" record in DNS for trying to deliver mail. This of course is not typically going to be the MX record for the particular domain. At that time the Domino box keeps the "A" record in the cache and will keep trying to send email to the "A" record. This of course bounces user's emails and causes me to have to stop and start the router to fix (clear the cache) issue.
This problem has been going since version 5 of Domino. It was apparent on the Win2k server and Win2003 server boxes that Domino had run on and is currently running on.
I have called Tech support and they tell me to add some lines in the notes.ini to hard code the dns servers addresses within Domino, but that does not help solve the root cause of the problem. The also mentioned this issue is with windows and the way DNS requests are being handled. I had an SPR created for this problem, but no resolution other than to have a program scheduled to restart the router.
This is getting very frustrating for me.
Ever since version 5. I am losing faith in Domino development and their inability to fix a major problem like this.
