Exclamation Help, after enable the "relay control" we can't receive the mail!


Dear all Linux user,

I am using RH 6.1, and the sendmail 8.9.3 for the mail server.

And after go to "netconf" and then go to the sendmail setting, enabled the "relay control" and added the "relay IP" by our mail, dns, firewall and internal network IP.

It can send mail to outside such as Yahoo, Hotmail etc. But if I try to send the mail to our mail server from Yahoo, Hotmail etc, it can't receive the mail from our mail server and display "ip does not like recipient, Remote host said: 551 we do not relay." in the Yahoo's mail.

Can anyone teach me how to setting the value by netconf?

Thanks.

I can't help you with netconf, but this may steer you in the right direction.
Do you have any kind of firewall set up within Linux? You can type ipchains -L to get that info. You can also look in the /etc/sysconfig/ipchains file. There are several different ways to go about resolving this. As a temporary fix, you can type ipchains -F which will flush the security settings. This is only temporary because your settings will be reset once the system is rebooted. It's a quick test if you aren't exposed to the external world. If that works, you can edit the /etc/sysconfig/ipchains file and make a entry for port 110 for pop3. You can duplicate the line for port 25 (SMTP) and change it to 110. This worked with RH 7.2.
