Re: qmail-smtpd => missing link => qmail-send
[In reply to]

If you send a message to a qmail server, and you are successful, than
you will se:
ok_250_XXXXXXXXX_qp_12331 <= and this is the queue-pid number, what is
comes up in the qmail-send logs.
If I make a connection to an qmail smtpd szerver, than I communicate
with the qmail-smtpd program, and this program sends back to me the answers.
From this, It seems to me, that qmail-smtpd sees the queue PID, which
can be the missing link. Only what we have to do, to somehow log this
into the qmail-smtpd log. (whitout mailforont, still don't like the idea)
This is right or not?
