[Reportbug-maint] Bug#586680: Misnamed option --tls/smtptls with misleading docs and missing SMTP+TLS support

--tls/smtptls should be renamed --starttls/smtpstarttls and the 
documentation should be corrected to note that the implementation uses 
STARTTLS not TLS when this flag is enabled. This type of connection is 
typically used on port 587. Updating the documentation to clarify this 
port number would be quite helpful and time saving for users.

The incorrect docs justify elevating the severity of this issue to normal.

A workaround for the lack of support for SMTP+TLS is to use 
SMTP+STARTTLS, typically on port 587, if available. Some providers do 
not support this.

The original wishlist item is support for SMTP+TLS; this could be 
enabled with a new flag --tls/smtptls (same as the old flag) with an 
implementation that does what --tls/smtptls was originally and 
incorrectly documented to do: SMTP over a connection that starts with a 
TLS handshake.

I have merged #586680 #740124 #412914 as they all report users 
struggling with SMTP+TLS on port 465.

Kind regards,
