No, ESMTP AUTH is different from pop-before-smtp. With ESMTP AUTH, clients
authenticate themselves via the SMTP server for each SMTP session. The POP
server is not involved at all.
The way the qmai-smtpd-auth patch works, if a client connects to the SMTP
server and successfully authenticates itself, the patched qmail-smtpd
process sets RELAYCLIENT for that session, thereby allowing relaying. When
the SMTP session is closed, the relaying permissions, along with the rest of
that process, disappear.
