Hi guys,

I have been getting the following error message when trying to send mail to apparently random domains.

-> Your message did not reach some or all of the intended recipients.

Subject: Joe Public
Sent: 10/26/2005 9:52 AM

The following recipient(s) could not be reached:
'Joe Public' on 10/26/2005 9:52 AM
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<exchange.mydomain.com #5.5.0 smtp;550 5.5.0 Mail rejected for policy reasons.>

The interesting thing is that sometimes I can send mail successfully to these domains, other times I get the above error.

This usally comes from being a spam blacklist. You may want to run your domain through the checkers at dnsstuff.com or other locations and try to get off the lists.
