[Users] Network Log - STARTTLS

[edwardp at gmx.com]

Have an inquiry regarding SMTP and noticed some differences in the
mail headers and based on what was noticed in Claws' Network Log, it
made me wonder if /perhaps/ there might be a configuration issue in the
SMTP server.

When the SMTP setting is set to use SSL/TLS on Port 465, the e-mail
headers resulting from it, indicate it was received from the host 'with
ESMTPSA', with the second 'S' signifying 'secure' and the 'A'
indicating 'authenticated'.

Using the same account, except changing the SMTP settings to use
STARTTLS on Port 587, the same e-mail header then references
'with ESMTPA', no second 'S'.

In checking Claws' Network Log afterwards for the STARTTLS session,
the SMTP server successfully received the STARTTLS command from Claws
and then it invoked a TLS connection.

If STARTTLS was successfully negotiated, shouldn't the e-mail header
from the second message also display the second 'S'?
