Subject: [PATCH] send-email: Describe 'ssl' and 'tls' in --smtp-encryption
Date: Sat, 14 Aug 2021 16:20:36 +0700	[thread overview]
Message-ID: <20210814092035.42272-1-bagasdotme@gmail.com> (raw)

The --smtp-encryption option accepts either 'ssl' or 'tls' value to
enable TLS connection. The latter can cause confusion (for example [1]),
because it means using STARTTLS, whereas users wanting SMTPS should set
to the former instead.

Describe these values, together with difference between SMTPS and
STARTTLS.
