First off, I'm a programmer without much experience in programming with network protocols.
That being said, I'm attempting to connect to a Postfix SMTP server using a secure connection. The instructions I received from the sys admin who set up the SMTP server were to do the following:
- Establish the connection.
- Issue an EHLO.
- Issue a STARTTLS.
- Enable TLS on the existing connection.
Is this a normal server setup? I would have thought that Postfix would be listening on a secure port that you can connect to directly rather than doing this whole starting plain text, switching to TLS deal.
