dubbin -> 5.7.1 Message Refused (26.Aug.2009 12:30:58 PM)

Exchange 2007 SP1

My User sends to Recipient & Recipient Receives Message
Recipient Replies & My User Receives Message

When my user replies to that reply the message bounces back with following information:

Servername.recipientsdomain.com #<Servername.recipientsdomain.com #5.7.1 smtp;550 5.7.1 Requested action not taken: message refused> #SMTP#

This is not only happening with this domain, it's also happening with Messagelabs clients but the bounce is different

server-4.tower-120.messagelabs.com #<server-4.tower-120.messagelabs.com #5.0.0 smtp;553-Message filtered. Please see the FAQs section on spam 553-at http://www.messagelabs.com/support/ for more 553 information. (#5.7.1)> #SMTP#

I've read through their support but have had no luck. Also, I am NOT on any Blacklists.

I can provide more information if needed.

Thanks in advance!

Please check the following things:

- is the ptr record in your external DNS correctly
- does the ehlo/helo your send connector send the correct external

Below you will have a link to a website which let's you check your ptr record:
