Hi,
I hope all are fine, we have exchange 2003 DC and also exchange 2003 server
and we are using GFI mail essential for downloading e-mails form our hosting
company. We have configured two domain names in it xyz.com and abc.com it
was working fine 2 months, but now we are facing the problem in sending
e-mail when we send any e-mail to hotmail,yahoo and gmail it is going but
others it is not going. After staying in the SMTP queue e-mails are
returning back with this message.
Your message did not reach some or all of the intended recipients.

The following recipient(s) could not be reached:
'123@xxxxxxxxxx' on 10/3/2005 12:29 PM
There was a SMTP communication problem with the recipient's
email server. Please contact your system administrator.
<exchange.Al-Subeaei.com #5.5.0 smtp;550 Denied by policy:
Sender is listed on DNS-based RBL.>
Can help me in this problem because now every e-mail is returning with this
message.

Siddiqui
