Sending mail relaying on Exchange Server

HCL Domino Domino Forum

Hi,

I have a Domino Server 8.5.1. It supposed to send mails through relaying on an Exchange server.

On server document, Outgoing SMTP Port is set to 25.

On configuration document, Relay host is given as [172.16.20.12] (Exchange ip address)

When an email is sent, an error comes on logs saying “Notes error: The remote server is not a known TCP/IP host”

This machine can “telnet 172.16.20.12 25”. No firewall problem.

Exchange server specialist says, Exchange is allowed for my Domino Server IP.

What can be the problem???

Thanks in advance.

Cakin.

Subject: check your connection document

you must have an SMTP connection document, listing:Source server = your Domino server, destination server = “Exchange”

SMTP MTA relay host = Exchange IP address Destination domain = the Exchange domain

With this document, the problem solved. Document gave error, “cannot connect to the Excehange server” and re-checking Exchange relay configuration solved… :))
