1) are you able to send email to this address from another server?

2) are you able to send email from your server to other addresses [hotmail, for example?]

You appear to have a mail loop on the local host. Check the users .forward to see whether they're doing something strange and also /etc/aliases to see whether there are any loops defined.

Thanks for all your reply, but I finally made it.
it had a file something wrong, sendmail.cw.
Sendmail.cw did not contain jbplaza.com so
I modified it and inserted jbplaza.com in it.

I have gotten the same problem mailing to cityofchicago.org

I honestly believe, based on my experience that its the target server at fault.

I will run another test when I get home, but unless outlook can send and linux can not, I believe the problem is external.

Good diagnostics:

sendmail -v -d8 -d38 help@jbplaza.com
type some text

.

This will get you enough enformation to run a traceroute. Assuming it doesn't slam into some DOS barrier and stop, you can see if there really are 28 hops from here to there.

The second diagnostic is a traceroute to the target mail server. To try and verify my theory, check your maillog after doing this send. Is the bounce coming from THEIR server or is your server complaining about hops. If its your server, you can fix that.

-v turns on verbose mode,
-d sets debug flags.
(8 get MX records for domain,
38 apply function to all symbol table entries)
