SMTP Auth connection delay
Using Plesk and Qmail on Fedora Core 3.
In Plesk, you specify SMTP Auth required.
There is a delay when connecting to the SMTP relay (20-30 seconds) before the email is accepted from the client machine.
I am trying to establish what underlying processes are involved in the AUTH process and acceptance of the email for relay in an attempt to reduce the delay.
Thanks

Sorted it.
If anyone is interested, the -Rt0 argument was added to the server_args line thus:
server_args = -Rt0 /var/qmail/bin/relaylock /var/qmail/bin/qmail-smtpd
Basically, this throws away the TCPREMOTEINFO request and sets the timeout to zero. man tcp-env for details.
