TLS 1.3
Idea shared by Chris - 6/23/2022 at 8:03 AM
Planned
We have rolled out Windows Server 2022 specifically to deploy TLS 1.3. 

There is a good post on here on how to enable TLS 1.3 QUIC for Webmail HERE
I believe MAPI/EWS is running through IIS so this should enhance those connections with HTTP/3 as well.

Upon testing, it looks like Smartermail is still running TLS 1.2 for SMTP and likely IMAP/POP too.

Requesting TLS 1.3 support for SMTP/IMAP/POP

I am sure it is coming, but they will need to move off of .net fwk to .net core.

Actually looking into it, it is something that looks like we can enable fairly easily for the TCP protocols. I'll add a note to discuss adding either to our upcoming production minor or at least to our next major version.
