Re: [mailop] Google rejects a TLS connection saying it needs TLS...

That's a custom rejection message set by that GSuite customer, no clue what
policy they set.

[mailop] Google rejects a TLS connection saying it needs TLS...

[Seth Mattinen]

Here's one I'm hoping someone can tell me I'm missing something obvious: 
Google is rejecting a TLS connection with an error saying to use TLS, 
but the connection is indeed using TLS.

What am I missing other than the suggested fax?
