!It is simply an SMTP exchange with TLS in a lower
!connection layer. The decrypted session is in no way
!different to a standard SMTP session once encryption
!has been initialized. What happens on the TLS level
!in detail is outside my scope; I am just a user of
!the SSL/TLS library here.

Here's what I'm seeing from a kernel trace/dump:

Note the 5 plain-text bytes "221 2" that are read from fd 3...

!Did you ask the GMail technical support about that
!problem?

I just posted this information to GMail technical support,
and will report back to the list if they respond.
