Do you use smtp-tls and smtp-auth at the same time? If Yes, then there are at least TWO reason for slow smtp-session. The first, DNS-related can be reloved by tcpserver's parameters. The second, tls-related - by creating temproraly RSA key, that can be done by executing
# make tmprsadh
at qmail source with applied tls-patch directory...
Quote: - when a 512 bit RSA key is provided in /var/qmail/control/rsa512.pem, this key will be used instead of (slow) on-the-fly generation by qmail-smtpd. Idem for 512 and 1024 DH params in control/dh512.pem and control/dh1024.pem. `make tmprsadh` does this.
try it and see if that helps you
