Here is what I set up this morning.  My mum uses only email, and 
doesn't surf the web.  So dial on demand wasn't something I wanted to 
try.  So I took this approach:

pkg_add -r postfix
pkg_add -r sudo

alter /usr/local/etc/postfix/main.cf to have:
relayhost = smtp.myisp.com

alter /etc/ppp/ppp.conf to have this within the myisp section:
   set server /var/run/istop "" 0177

create a dial script for mum:

run visudo to add this:
mum   ALL = NOPASSWD: /usr/local/sbin/postfix flush
mum   ALL = NOPASSWD: /usr/sbin/ppp -quiet -background myisp
mum   ALL = NOPASSWD: /bin/kill -TERM `cat /var/run/tun1.pid`
mum   ALL = NOPASSWD: /usr/sbin/pppctl /var/run/myisp quit all

Create a "dial" script:
sudo /usr/sbin/ppp -quiet -background myisp
sudo /usr/local/sbin/postfix flush
sudo /usr/sbin/pppctl /var/run/myisp quit all

Create ~/.fetchmailrc:

poll port 12346 with proto apop:
    preconnect "ssh -f -L 12346:my.mail.example.org:110    
    [EMAIL PROTECTED] sleep 40 </dev/null >/dev/null"
    password secret;

In this case, all of mum's email goes to my mail server, and sits 
there waiting for her to pop it off.  This is done via fetchmail.

So after Mum types her email and "sends" it, she exits pine, then 
issues the "dial" command.  I'm going to add some error checking to 
the above "dial" script.  Especially to check that ppp connects.

Any suggestions?

FWIW: she's not yet using this as we're waiting for her dial-up 
account to be set up but I've tested it using her DSL provider's dial 
up line.
