Hi This is a repeat of an earlier thread. I am using mozilla as my email program and esmtp with tls to connect to courier. The time I have to wait is 60-120 seconds before the smtp hand shake starts. I have tested DNS using "host" and the delay for host is less than 5 seconds.

Forwards AND backwards?

An incoming ESMTP connections results in: a reverse DNS lookup on the client's IP address; a forward DNS lookup on the result; and identd query to the incoming IP address.

What could I do to speed up the connection time?

Disable DNS lookups and identd queries.
