Many services are beginning to deprecate TLS 1.1. I am creating this issue to confirm that 1, the SMTP module will continue working with services that do not use TLS 1.1.
I recall this issue causing quite a bit of consternation #2983132: Error since Mail Provider turned off TLS 1.0 support. → and I just wanted to be proactive this time.
I was made to think of this as I received a notice from Sparkpost that they will be deprecating TLS 1.1 in September.

From AWS:
"We will begin deploying updates to the TLS configuration for Amazon CloudWatch Log APIs to a minimum of version TLS 1.2 by September 15, 2023, even if you still have connections using these versions. These deployments will complete by no later than December 31, 2023. This update removes the ability to use TLS versions 1.0 and 1.1 with all AWS APIs in all AWS Regions [1]."
