Hello,
I have a newly-installed Exchange 2013 SP1 server (all roles installed on one server) that I installed CU6 on, and now the incoming mail flow has stopped. Incoming mail is rejected at SMTP time with the following message:
"451 4.7.0 Temporary server error. Please try again later. PRX5"
From the logs, I traced it back to the Transport Service "Default SERVERNAME" receive connector, which is configured to listen on 0.0.0.0:2525. Here are the relevant log snippets:

When I try telnet'ing to localhost:2525 (or the actual IP of the exchange server), I either get an initial connection that drops after I hit any key, or I get connection refused.
I have confirmed that the "Default SERVERNAME" connector is configured appropriately, under the HubTransport role, listening on 0.0.0.0:2525:

And I've already tried the hosts file trick, with no change to this behavior.
It's probably worth noting too that this is *not* intermittent behavior -- this happens with every single email that is sent to the frontend (TCP/25) receive connector.
I've also confirmed that my components are all active:

Any assistance at this point is greatly appreciated. I've spent 3-4 days just getting this system up and importing 37GB of mailboxes to it -- reinstalling at this point is not something I'm looking forward to doing (not to mention the fact that all incoming email is just queuing up at a backup MX while I'm waiting for this to go live...). Thanks!
Regards,
Jon Heese
