How to enable TLS 1.2 on Mail 16.0 (Monterey OS) My mail provider IONOS moved to TLS 1.2 and I started to fail sending mails. Even deleted and added again my mailbox, but nothing help. Even at advanced settings see no option to name secured ports numbers. In TLS Cerificate see the only option - "None"! Apple! How it could be?

Can't Encrypt Email Message Warning The mail app on Ventura 13.2.1 keeps warning me that I don't have encryption certificates for my message recipients. I am not trying to send encrypted e-mail - why does Mail keep warning me about something I'm not trying to do?

macOS Mail does not support TLS 1.3 SMTP/IMAP connections Hi, this is pretty much a bug report. Hope it gets to the right place. I run my own mail (SMTP+IMAP) servers and configured them to accept only TLS 1.3 connections from clients. Both SMTP and IMAP connections from Mail.app on Ventura 13.0.1 subsequently broke with TLS negotiation error in Connection Doctor, however the Mail app on my iPhone (iOS 16.1.1) continued to make connections and the servers reported them to be TLS 1.3. I then re-enabled TLS 1.2 on my servers and macOS Mail.app could again make SMTP and IMAP connections. It seems that macOS Mail.app (and maybe perhaps other apps?) aren't TLS 1.3-enabled.
