why use sendmail if you have already postfix to do it?
regarding to your demand dialing outgoing mail problem, why not point your outgoing
mail to your isp smtp instead using your local smtp. this trick will offload some
resources on your server. every time your workstation send an email, it will
directly send to your isp smtp instead to your local smtp. so that you dont have to
worry queued emails.
here's the trick on how to do it in your dns:
let say this is your isp smtp ip address
smtp.ofyourisp.net in a 1.2.3.4
and assuming you are using 192.168.0.0/24 block on your local lan and this is the
entry on your dns forward database file
server.yourdomain.net in a 192.168.0.1
smtp.yourdomain.net in a 1.2.3.4
fooler.
