Cleavis,

Relaying by http proxy is not a very good idea, as it can leave you open to spammers using your system. If you are running an older version of apache this is the first thing that will happen after a compromise.
It is possible to restrict your proxy access via the allow/deny statements:

#<IfModule mod_proxy.c>
#    ProxyRequests On

#    <Directory proxy:*>
#        Order deny,allow
#        Deny from all
#        Allow from .your-domain.com
#    </Directory>

However you would be better advised to use a proper MTA such as postfix/sendmail/exim to route your mail.

Cleavis,

are we talking about controlling relaying access on the SMTP server, or controlling access on Apache.

What is your smtp mail server product and version.  You could get it by doing a "telnet youipaddress 25", and type in "helo whatever".

cheers.

Hi cleavis,

This is sendmail problem.  You may get a much better solution is you either request the question to be move to Sendmail area (http://www.experts-exchange.com/Networking/Email_Groupware/Sendmail/).

I would try to help (as much as I could).

I would assume that the error is coming from Sendmail at abc.com.  And this is normal because you had attempt to relay the mail to xyz.com.  In order to do this, you could either;

Configure the sendmail on abc.com, to allow relaying from xyz.com;
or.  Configure your mail client, to use mail.xyz.com as the SMTP server.

Please could you post the complete SMTP header of the bounced mail. (you may change the real hostname and IP address).

Cheers,
