When I send a message to a mailman 2.1.4 mailing list using Postfix from a yahoo account. I receive an error message that says "No route to Host". It seems when I send out a message from our domain "isu.edu" they are received, but from any other smtp host I receive the below error:
/var/log/maillog:Mar 17 01:55:24 lx5 postfix/smtp[16457]: 10F74124A31: to=wheakorypersonal@yahoo.com, relay=none, delay=4956, status=deferred (connect to mx4.mail.yahoo.com[216.155.197.63]: No route to host)
Here's my main.cf using postconf -n ( would really appreciate help this is critical). (I've been working on this for 15 hours straight and don't have any more troubleshooting ideas)

The error itself is neither a postfix issue nor a mailman issue. "No route to host" means what it says. Check your routing and firewall configuration; your "lx5" machine needs to be allowed to establish connections to port 25 at arbitrary IP addresses in order to distribute mail. You may already have a well-defined set of outbound mail servers that are allowed to do this, in which case you should either configure mailman to use them, or add lx5 to the relevant firewall list. Outbound connections to port 25 may be blocked to slow the spread of email worms.
