Support Implicit TLS for sending emails

Previously, TLS could only be used with STARTTLS. Add a new option `implicit_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>
