Paul,

To me it seems that everything should work just fine but yet it fails.

Prior to during on debugging for the IPs in question the only error in
the logs was the following.
smtp1 postfix/smtpd[15062]: connect from tnpsan1.(domain).com[10.12.0.101]
smtp1 postfix/smtpd[15062]: lost connection after HELO from
tnpsan1.(domain).com[10.12.0.101]
smtp1 postfix/smtpd[15062]: disconnect from
tnpsan1.(domain).com[10.12.0.101]

Both the postfix and the server sending are on the same /24 network and
on the same switch. I have checked for an ACL or other issue but there
is nothing network related which I can find that I believe would prevent
connection as desired. There is no local firewall, virus software or
anything on the sending machine and selinux has been disabled on the
postfix server without resolving the issue. The other item that seems
strange to me is I have other machines in the same subnet which are able
to send without issue.

Thanks,
Blake
