I'm a simpleton.. but from your description it sounds to me like you have each and every client workstation pop'ing their mail from your third party...
"We do not have IMS running on Exchange but have been able to send and receive internet email for years. " maybe your third party updated/changed something? maybe it may thinks your trying to relay thru them (I've had troubles with covad's mail servers think that on occasion) maybe a quick telnet to the POP and SMTP server on the third party to see if you can communicate with it in general?? just some ideas bill -----Original Message----- From: Chris Scharff [mailto:[EMAIL PROTECTED] Sent: Friday, July 11, 2003 10:51 AM To: Exchange Discussions Subject: RE: Internet Email What does the NDR say? -----Original Message----- From: Rob Talkington III [mailto:[EMAIL PROTECTED] Posted At: Friday, July 11, 2003 8:19 AM Posted To: swynk Conversation: Internet Email Subject: Internet Email This is the first time I've posted here and I couldn't find a search function. I use Exchange 5.5 SP4 and Outlook 2000 clients. We have our email hosted by a third party but use Exchange locally. Monday I came in and for some reason no one can send internet email anymore. Receiving it is fine but sending it generates a Non Delivery Report immediately after clicking on "Send". I did not change anything on Exchange the weekend prior. I have searched many discussions and cannot find an answer that pertains to our problem. Any advice would be much appreciated!! Thanks!
