qmail works fine, best not to tamper with it
The problem is the way a connection is established when you use a dialup line.
As soon as a DNS request is made (UDP port 53), then diald will up the link to allow the DNS request to be serviced. You can add a line to diald.filter which will tell diald to ignore any DNS lookups. I think Stephen Noble originally came with the line in diald.filter:
#no udp for e-smith-isp
ignore udp any
This line tells diald to ignore any UDP request (which will include a DNS lookup).
What you need is a similar line in diald.filter to prevent diald from bringing the link up when mail is directed outside your local network.
I would imagine that the line to add will be something like:
ignore tcp tcp.dest=tcp.smtp
This should prevent a dialup when there is only outgoing mail. The mail will be sent next time the link is up.
I cannot test it now, but you may wish to try it and report back
