Thread-topic: Issues sending to gmail today?

Hmm, those two IPs are not listed in gmail.com or google.com MX. Does the recipient domain have those two IPs listed? I wonder if there is a STARTTLS requirement on that domain.

Is anyone else seeing this behavior today?

We're seeing this behavior across a number of MTA hosts that have never had this issue before. Most messages go through except for those that hit either 74.125.201.109 or, 74.125.201.108
Here's a snippet from our postfix logs.
