mail loops back to me (MX problem?) OR did not issue MAIL/EXPN/VRFY/ETRN

Hi all,

If you are receiving "mail loops back to me (MX problem?) Local configuration error" (in client side) or "did not issue MAIL/EXPN/VRFY/ETRN during connection to ..." (server side /var/log/maillog) message while sending email to another email address?

I have found that this is usually causes from the hostname of mail server is set to "localhost.localdomain"

I hope this will work.

This can mean that the client did not issue any commands. If you login to your smtp server using

Code:

telnet localhost smtp

and then just type quit, then the log will show a message like that.

These types of errors usually occur for me when the client is not correctly configured to deal with the server... can't come up with a good example right now though...

The error arises when your server's hostname is set to "localhost" or "localhost.localdomain". Just change the hostname of your email server and check. I think it will work.

Any other ideas? My hostname is set correctly (checked in config file and running "hostname", to make sure it hadn't been changed)....but I'm still getting this error.

Thanks,

check your /etc/mail/sendmail.cf and see how the default mail is set to
verify your /etc/aliases

then lookup your mail server and verify those are correct

Code:

nslookup
set type=mx
$domainname

When I enter $domainname, I get the following error: *** Can't find $domainname: No answer

When I enter my servers domain name instead, I get the same mail exchanger as I do when I enter "host domainname", which is "mail.domainname.com".

*Domainname.com is replaced with the real domain.

Sorry I didn't specify, it was supposed to be your domain. Did it pull
Up the right mail server?
