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:
recipient@recipientsdomain.com
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
recipient@recipientsdomain.com
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!
