We've been having delivery issues to gmail since November 15 at 12:17 pm (Central). But there's still lots of email going through, too. Here's an example from our mail server's logs: Failed rr=Site gmail.com (2607:f8b0:4001:c5a::1a) said after data sent: 550 5.7.1

Your hypothesis is accurate; speaking from professional experience with Proofpoint products, there is an option within the Proofpoint PoD DKIM signing configuration to set the Domain scope to "Any" which will reproduce this behavior if someone just left the defaults when generating a key(s).

It could even be as simple as the use of TLS being a datapoint for their filters, and the change in that datapoint was enough to either improve a score or modify a fingerprint enough to change the bucket the messages are classified in. Mike -Original Message- From: mailop On Behalf

Hi, Two things can be true at the same time. The OP did not say that you will never have deferrals once you turn on STARTTLS. He said that he had deferrals without STARTTLS that went away with STARTTLS. It is definitely possible that STARTTLS influences behaviours and limits, just as IPv4 vs

We use an MTA which supports STARTTLS, sending the message data through an encrypted channel for servers which support it (like Google). Thank you for enabling opportunistic STARTTLS - you've stepped up the game for both yourself and possible clients. However, it is not something that will
