After some time 15 minutes I'd guess, the emails finally sent, but there is still a delay, I've got another test email just sitting in queue right now. The IP address has not changed, and I double checked my DNS records, and they point to the same IP address as the Exchange server. Even internal emails are delayed by 30 seconds to a minute. 0 Mace OP Gary D Williams Dec 7, 2014 at 12:44 UTC Anything in the event logs of the client or the exchange server? 0 Poblano OP kyle_chambers Dec 7, 2014 at 12:44 UTC No, that is the single most frustrating thing... jsut the mail queue error is all there is. 0 Mace OP Gary D Williams Dec 7, 2014 at 12:50 UTC Is dns working on the exchange server?

I have a 3-node network, External, Perimiter (DMz), and Internal. This is confugured utilizing Microsoft Threat Management Gateway 2010. I have a split DNS infrastructure. My internal network has Active Directory and the DNS forwards requests to my Perimiter DNS server. My permiter DNS server forwards requests to Google PUblic DNS 8.8.8.8. This seemed to work http://forums.msexchange.org/Sending_Mail_External_Fails_-_Message_in_Queue/m_1800601499/tm.htm a bit better than using my ISP DNS. I can send email internally between users with no issues. I have created a Send connector as described in a MS article for all other domains. I'm seeing in my TMG firewall logs that the SMTP from the exchange server is not getting denied and it is resolving to gmail. This is the error in the NDR: Remote Server at gmail.com (2a00:1450:4013:c01::1a) returned '400 4.4.7 Message delayed' 12/29/2014 1:16:01 AM - Remote Server at gmail.com (2a00:1450:4013:c01::1a) returned '441 4.4.1 Error encountered while communicating with primary target IP address: "Failed to connect.
