URGENT: Mail Issues

[Amja]

All,

I have the following issues in the Coldfusion Server. In the mail log I'm
seeing the following issues logged. Where all the emails are valid emails. I
just made them xxxx, yyyy inorder to protect their identity.

Invalid Addresses; nested exception is: class javax.mail.SendFailedException:
554 <xxxx@hotmail.com>: Recipient address rejected: Relay access denied
Mar 29, 2007 ? 9:36 AM ? Error ? 0 ? ?
Invalid Addresses; nested exception is: class javax.mail.SendFailedException:
554 <yyyy@gmail.com>: Recipient address rejected: Relay access denied
Mar 28, 2007 ? 8:18 PM ? Error ? 0 ? ?
Invalid Addresses; nested exception is: class javax.mail.SendFailedException:
554 <zzzz@yahoo.com>: Recipient address rejected: Relay access denied
Mar 28, 2007 ? 8:02 PM ? Error ? 0 ? ?
Invalid Addresses; nested exception is: class javax.mail.SendFailedException:
554 <pppp@yahoo.com>: Recipient address rejected: Relay access denied

And many more such entries. Any idea what is going wrong???

Relay Access Denied is a security restriction that is set by the SMTP server.
On the SMTP server you restrict relaying by IP, domain, subnet etc... Try and
contact your SMTP Server Administrator to ensure that 'relaying' is allowed for
the machine that CF is on or try a different mail server.
