Hotmail returning emails

[msinni]

I have been having problems with hot mail returning mail from my users. Can someone point me in the right direction? Here is what I found in the event log. Thanks



This is an SMTP protocol error log for virtual server ID 1, connection #8. The remote host "65.54.244.200", responded to the SMTP command "mail" with "550 OU-002 Mail rejected by Windows Live Hotmail for policy reasons. Reasons for rejection may be related to content with spam-like characteristics or IP/domain reputation problems. If you are not an email/network admin please contact your E-mail/Internet Service Provider for help. Email/network admins, please visit

for email delivery information and support ". The full command sent was "MAIL FROM:<sinnim@vfservices.com> SIZE=1146 ". This will probably cause the connection to fail.





A non-delivery report with a status code of 5.5.0 was generated for recipient rfc822;xxds@hotmail.com (Message-ID <3FB966A61AF2A7458F9663187D9FBA13011F1585@vnt.xxxx.xxserervices.com>).
Cause: This message indicates a generic protocol error (SMTP error). For example, the remote SMTP responds to an issued EHLO with a 500 level error and the sending system will QUIT the connection and report this with NDR indicating the remote SMTP server canÆt handle the protocol.
Solution: View the SMTP log or run a netmon trace to see why the remote SMTP server rejects the protocol request.

I am having the same problem and yes I have verified everything.

Make sure you have both an RDNS entry and an SPF record in your public DNS. That should resolve this issue for you. Also verify that you are not listed on any RBLs.

I hope you find this post helpful.
