We're Running an Exchange 2003 Server, It's been running since about Nov. 2003, and haven't had any problems sending or recieving mail until now.
All of our mail is being sent successfull, except for mail sent to yahoo.com and aol.com
It's not sending back bounce messages, or anything of the sort.
When I look at the job que, and click on the yahoo que or aol que, it says "The connection Was dropped by the Remote Host."
I'm not seeing any NDR's being sent back, it just keeps retrying, until the message expires.
I've checked spam lists, and am not on any of them that I can find.
Has anyone run into this?
