IIS SMTP unable to relay for domain on local network.
- by MartinHN
Hi
I have a network with the following servers:
EXCH01 - Exchange Server for @domain.com e-mails.
TEST-REP01 - Local reporting server. Have IIS SMTP installed and configured.
What happens on the TEST-REP01, is that I have a Windows Service that reads reports in a SQL server that is ready for delivery. All reports is sent one at a time, using the local SMTP server.
It works perfectly, unless the recipient e-mail address is [email protected] - the domain that the EXCH01 server manages.
I get the following error:
Mailbox unavailable. The server
response was: 5.7.1 Unable to relay
for [email protected]
What can I do to troubleshoot this further? I can't seem to find useful information in the SMTP log:

Relay access on the local IIS (TEST-REP01) are set to allow 127.0.0.1, TEST-REP01 and other servers such as TEST-WEB01.
DNS settings on the local network is not domain.com - but companyname-domain.local.
