Have there been any updates? My email provider also requires that the client automatically establish a TLS connection on connect on port 465.
How do I tell Discourse to use this option?
To be precise, in [swaks](https://linux.die.net/man/1/swaks) this is called --tlsc
--tlsc, --tls-on-connect
Initiate a TLS connection immediately on connection. Following common convention, if this option is specified the default port changes from 25 to 465, though this can still be overridden with the --port option.
