Hi there,
I also think it is the tcpserver switch used. I had to set mine from -
H (which will keep qmail-smtp from doing reverse lookup) to -h (which
is the default and does allow for lookups).
Mark that I also use a caching DNS server (tinydns), which is a good
thing to have in this
#!/bin/sh
QMAILDUID=`id -u vpopmail`
NOFILESGID=`id -g vpopmail`
MAXSMTPD=`cat /var/qmail/control/concurrencyincoming`
exec /usr/local/bin/softlimit -m 800 \
/usr/local/bin/tcpserver -v -H -R -l 0 \
-x /home/vpopmail/etc/tcp.smtp.cdb -c $MAXSMTPD \
-u $QMAILDUID -g $NOFILESGID 0

A good pick up by Tren, I didn't think about tcpserver initially. As far
as I know, the only reason you will experience any sort of delay is if
the dns that the accepting server is not functioning properly. I have
taken to running a copy of dnscache on each of the front end
