Thank you! I had read pretty much the same information using this link:

http://www.postfix.org/faq.html#dialup

Reading it again reinforces what I have learned from this section at Red Hat:

http://www.redhat.com/support/resources/howto/RH-postfix-HOWTO/c241.html

The part at postfix.org about checking to make sure the buffer gets
flushed confuses me a little -- they  have written a little script to
make sure each message gets flushed out using the sendmail -q command,
but it looks like all it does is keep the script busy until the queue
is empty. I gather this script might go in the ip-up.d directory to
keep the connection up until the messages are all sent ...?

I have her ppp connection to NOT start on demand, so maybe I can leave
out the defer_transports setting in postfix. (In other words postfix
can not make the phone dial when she queues a message offline, so I
don't have to stop postfix from trying.) That way I won't have to put
sendmail -q in crontab. Not that it would be difficult, but for the
purposes of my HOWTO I want to touch as few files as I can.
