odd error

[drdre]

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:

francoise@usc.edu.tt
SMTP error from remote mail server after RCPT TO:<francoise@usc.edu.tt>:
host mail.usc.edu.tt [200.1.110.124]: 450 4.7.1 Client host rejected:
cannot find your hostname, [50.22.48.160]: retry timeout exceeded"


Any ideas ?

I guess the email address you've mentioned in this post is valid? If it is I'd suggest you modify it unless you're trying to get him on a spammers list.

Surely the error message tells you what the problem is? The usual reason is the DNS records and/or rDNS are incorrect. Take your pick: +"450 4.7.1 Client host rejected: cannot find your hostname" - Yahoo! Search Results
