mail loopback

[warcries]

hi guys,

I'm having a problem when using a relay host. I used the web-console to configure the RELAY HOST. But when I send a message, it says: mail from x.example.com loops back to myself.

What is the possible reason of this problem?

Hoping for you help.

thanks in advance.

regards.


NOTE:
I'm using 6.0 for my mail server.

You need to update your forum profile with the output of the following command (do not post the output in this thread):

zmcontrol -v

It could be a number of problems. What happens if you revert the changes, does it work correctly? You could have a mis-configured DNS server or you could have made an error setting the relay host. Is this a single server or multi-server? Is the relay host in the same domain (is this a split domain set-up)? You should also post the error messages from the log file not a single line out-of-context.

When I revert the changes. it's working perfectly. What do you mean by a mis-configured DNS? What should be my DNS configuration with regards to RELAY Host? This is just a single server setup and RELAY HOST is in the same domain. I'm not familiar with split domain set-up?
