Hi All,
We have been running Exchange 2010 for some time now and never had any real issues with it. We have recently employed the services of a new E-Marketing company and they are trying to say we are blocking messages
from them. Our previous company had no issues though. We set them up a new domainthat isn't linked to our own and I have added all required domains (the new and their internal domains) to the exceptions on our Firebox firewall. When we send out a campaign
IE; an e-shot to say 45 external and internal people via their system, some recipients receive the messages and some don't. The e-marketing company
say they are seeing the following NDR at their end for some recipients:
__RECEIVED_LOCALLY__,2013-02-12 16:08:12+0000,,e-mail address of sender,e-mail
address of recipient,,,,,,,smtp,localhost (127.0.0.1),,,,,,VMTA-BRONZE,,,,,127.0.0.1,127.0.0.1 __BOUNCED__,2013-02-12 16:08:29+0000,2013-02-12 16:08:12+0000,e-mail
address of sender,e-mail address of recipient,,failed,5.0.0 (undefined status),"smtp;571
Delivery not authorized, message refused",our webmail address (our
external IP address),policy-related,smtp,localhost (127.0.0.1),smtp,senders IP address,our external IP address,"8BITMIME,SIZE,AUTH",42473,VMTA851,,,cosatto.com/VMTA851,VMTA-BRONZE,,
(I have removed some information in the bolded fields)
My argument is that the recipients sometimes receive the messages and sometimes they don't, it's very sporadic! So how can we be blocking them in any way? We don't have any filtering
/ edge subscription within our Exchange server so am baffled as to how we could block anything from them???
Any help / advice GREATLY appreciated!
Cheers
