Curious, and it couldn't be connection cache/reuse or something?
Your Postfix SMTP server logs would contain one smtpd 'connect'
event with multiple smtpd "QUEUEID: client=name[address]" events.
That's basically what I see. A few connect-events and a ton of
"sasl_username" client-events. So the same connection is being reused by
the client to just keep the connection open and send mails, bypassing
any password changes or account deletion. Is there some way to prevent
this? Perhaps have the connection die after 10 seconds, forcing a
re-auth?
