Thanks.  I tried that, but it did not seem to have any effect.  The command I 
used was:

iptables -t mangle -A OUTPUT -j MARK --set-mark 0x0a -p tcp --dport 25

Now, when connecting from the localhost, I get:

telnet: connect to address 66.33.196.49: No route to host

I can still connect via the NAT'd systems okay.

Thanks for the assistance!

John.
