recordio is a neat little program that comes with ucspi-tcp-toaster. When
you plug it into the smtp (or any other for that matter) process, it records
all of the input/output of the smtp session to the smtp log. Note, it can
grow your log quite rapidly on a busy server, so you don't want to leave it
on for a long period of time.
To enable recordio, modify your /var/qmail/supervise/smtp/run file as follows:
exec /usr/bin/softlimit -m 12000000 \
/usr/bin/tcpserver -v -R -H -l $HOSTNAME -x $TCP_CDB -c "$MAXSMTPD" \
-u "$QMAILDUID" -g "$NOFILESGID" 0 smtp \
/usr/bin/recordio \
$RBLSMTPD $BLACKLIST $SMTPD $VCHKPW /bin/true 2>&1
Note, we simply added the next to last line here, leaving everything else as
is. Then
# qmailctl restart
to restart the smtp process, and run a test. You'll see the details of the
smtp session in the smtp log file (current). Once you have a sampling,
remove recordio from the run file and restart qmail again to turn it off.
