Jan Schär	e8519e0ed2	Support Implicit TLS for sending emails (#13317) ... Previously, TLS could only be used with STARTTLS. Add a new option `force_tls`, where TLS is used from the start. Implicit TLS is recommended over STARTLS, see https://datatracker.ietf.org/doc/html/rfc8314 Fixes #8046. Signed-off-by: Jan Schär <jan@jschaer.ch>	2022-07-25 16:27:19 +01:00
Richard van der Hoff	8f98260552	Fix incompatibility with Twisted < 21. (#10713) ... Turns out that the functionality added in #10546 to skip TLS was incompatible with older Twisted versions, so we need to be a bit more inventive. Also, add a test to (hopefully) not break this in future. Sadly, testing TLS is really hard.	2021-08-27 16:33:41 +01:00
