I would think it would start working as soon as it's active (service is running) and you have 127.0.0.1 listed first in your /etc/resolv.conf.

Re: [qmailtoaster] Re: Problem sending mail to comcast.net
I found this in the archives.
All of the senders experiencing the bounced
messages mentioning cname lookup failure appear to be
running the qmail mail server software. Qmail, if not
using a third party patch that was written in the late
90's, has an issue sending to domains whose name
servers respond to DNS queries of type "ANY" with more
than 512 bytes of data; that is a bug in qmail and the
author has never fixed it because he wants you to use
his DNS server software which also eliminates the
issue in a different way. Google's name servers do
respond to queries of type "ANY" with more than 512
bytes of data, so when an unpatched qmail server tries
to send an email to a domain whose lowest cost MX
record ends in .google.com, qmail is going to do a DNS query of type ANY
against one of google.com's
authoritative name servers, get back more than it can
correctly handle and defer repeatedly until ultimately
bouncing the message with that cname lookup failure.
