Centos 6 Postfix 1 IP Two Domains Two Machines

Hello Folks,

I have what I believe is a basic problem. I'm sure the problem is related to my incorrect understanding of the terms used by the postfix main.cf file.

I have two mail servers. 192.168.1.110 (msrecycle.com) and 192.168.1.111 (sportbikebody.com). Now what I am trying to do is have any mail for sportbikebody.com forwarded from 192.168.1.110 (msrecycle.com which is server that gets all pop3 smtp imap etc traffic from the router) to 192.168.1.111. I would love to simply forward the ports to two IPs but cannot do that with my router.

FYI HTTP is working correctly and accesses the correct server for each domain.

I know I am close because I see the log on the .111 address receiving the mail but it appears to try any resolve the sportbikebody DNS and does so which gives it the external address and therefore I get a too many hops message. I hope this is clear. Let me know what you guys want to see.

Here is tail of the log from .111 (sportbikebody.com)

Here is the error message

I am actually a body guy - I am the painter for both these domains so if you own a sportbike (or just a plain old motorcycle) and you can help me work out a few issues I am having I'll be happy to remember it when / if you need repairs.

postfix-add-filter

POSTFIX-ADD-FILTER(8)					      System Manager's Manual					     POSTFIX-ADD-FILTER(8)

NAME

       postfix-add-filter - add filter service to Postfix master.cf

SYNOPSIS

       postfix-add-filter [smtp service name...] [smtpd port...]

DESCRIPTION

       The  postfix-add-filter(8)  command  adds an smtp service named smtp service name and and smtpd server listening on smtpd port to etc/post-
       fix/master.cf to facilitate integration of SMTP filters such as amavisd-new or clamsmtp.  The configuration is based on the upstream recom-
       mendations for amavisd-new 2.6.0.  Adminstrators should verify it is appropriate for their requirements.

       The original file is copied prior to modification and left in /etc/postfix to make it possible to revert changes easily.

       Available in the Debian package for Postfix version 2.5.3 and later.

DIAGNOSTICS

       If  the given smtp service name or smtpd port already appear in the master.cf, a message will be printed to standard out and master.cf will
       not be modified.

ENVIRONMENT

       MAIL_CONFIG
	      Directory with Postfix configuration files.

	      The postfix-add-filter(8) command should use this, but it currently doesn't.  It is hard coded  to  /etc/postfix.   This	should	be
	      changed.

CONFIGURATION PARAMETERS

       None

FILES

       /etc/postfix/master.cf
