Verify and program if it is the case if support all TLS options as nodemailer use

[cesarjorgemartinez]

Options using by node:
https://nodemailer.com/smtp/

TLS options
secure – if true the connection will use TLS when connecting to server. If false (the default) then TLS is used if server supports the STARTTLS extension. In most cases set this value to true if you are connecting to port 465. For port 587 or 25 keep it false
tls – defines additional node.js TLSSocket options to be passed to the socket constructor, eg. {rejectUnauthorized: true}.
ignoreTLS – if this is true and secure is false then TLS is not used even if the server supports STARTTLS extension
requireTLS – if this is true and secure is false then Nodemailer tries to use STARTTLS even if the server does not advertise support for it. If the connection can not be encrypted then message is not sent

keystone spassword uses common python library smtplib not nodemailer (for node?)

According with documentation about smtplib https://docs.python.org/2/library/smtplib.html there are not special optiosn for TLS
