I am getting this error when trying to send an email to one of our customers..
"This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
SMTP error from remote mail server after RCPT TO:<firstname.lastname@example.org>:
host mail.usc.edu.tt [220.127.116.11]: 450 4.7.1 Client host rejected:

Any ideas ?
