With this setting, e-mails are only sent when STARTTLS is supported by the service
provider.
STARTTLS uses ports no. 25 and 587.
To use STARTTLS a certificate is required.
With this setting, e-mails are also sent when STARTTLS is not supported by the
service provider. In this case the transfer can also be unencrypted.
If the service provider supports STARTTLS and TLS is negotiated, the certificate of
the service provider is trusted and encrypted.
