"Domain of sender does not exist"!!!

[ajd]

Hi

I'm setting up an R5 server on a W2K server. I'm planning on using this as an upgrade/replacement for a 4.6 server running on NT 4.0 [separate physical machines].We are a small office and have only 1 Notes server for 30 users.

I created a Notes directory on the W2K machine & copied over the Notes\Data from the 4.6 machine.

I then installed R5 into this Notes & Notes\Data directories, using the cert.id, server.id and an admin user.id from the 4.6 machine.

I can send e-mail messages internally OK, and can receive e-mail messages from people outside of the office OK. But when I try to send e-mails OUT of the office I get a Delivery Failure with the following message

Error transferring to mail.**.ORG; SMTP Protocol Returned a Permanent Error 501 5.1.8 <Tony_Dempsey/Nche@NCHE.EDU>... Domain of sender address Tony_Dempsey/Nche@NCHE.EDU does not exist

Our e-mail address in the office is user@aacn.nche.edu
we are a subnet of another larger organisation [NCHE.EDU] who run the routers, DNS servers etc.

But if the configurations between the existing 4.6 and R5 servers are the same, then why am I having problems?

For the test, I did shut down the 4.6 server, and assign its IP address to the R5 server.

THanks for any help

Tony

Notes made definitive changes between SMTP mail handling in R4 and R5. If you are upgrading to notes R5 you also have to upgrade your clients.

I had the same problem and found out that my DNS was pointed to our own Proxy server which did have DNS Host entries and did allow similar actions as what you have described. But I allways got the same messages that you described. 2 things resolved the problem, 1 was setting the right DNS record and the other was the DNS lookup setting on the Lotus server. For some reason even though it was pointing to an outside DNS server some of the e-mails would get bounced because I had DNS look up verification enabled.

Hope this helps
