Email server 450 host down
Posted on 2004-04-06
We are running Groupwise 6.5 on a windows 2000 server. It has had no problems until about one month ago. We keep seeing the follwoing message in our Groupwise Internet Agent logs:
11:50:02 10 DMN: MSG 413 Send Failure: 450 host down (yahoo.com)
The host down has been several different domains but one has been an external email address that we use as a back up email account. We have contacted the provider and they say everything is working ok on their end and it must be our problem.
Additionally even though the email server reports the host down, the email sent to that domain does get to it, occasionaly.
can someone help out.??
