Thank you for the suggestion... I actually discerned a complete set of
postfix settings that seemed to work perfectly. Local mail was being
delivered correctly, remote mail was being delivered correctly, AND I
had gotten things fixed so delivery attempts worked correctly when the
computer was online or offline. Postfix apparently worked beautifully.
I plan to update the wiki in case someone follows in my footsteps....

HOWEVER I finally gave up on ppp mail delivery when I discovered that
fetchmail wasn't working at her house! Actually it would work
correctly for me when I was tinkering with it, but after each reboot
and subsequent ppp connection, fetchmail would fail to resolve the
host, even after letting it sit through numerous attempts. (I could
ping and otherwise "see" the IMAP host from other processes, but
fetchmail could not.)

It would start working if I tinkered with the postfix settings and
restarted it while the machine was online. Since the ip-up.d script
ALREADY starts postfix after the connection is up, I decided it was
obviously too flaky to turn over to my mother-in-law.

SO I sacrificed my principles and told her to ignore the IMAP errors
Evolution displays when the system is not connected to the Internet,
or if they bother her, to click the little icon (that she can barely
see) in Evolution to switch between online and offline mode. It's not
ideal. My next step will be to switch her email to a server she can
POP from, which will at least remove the IMAP errors. I can't see any
way to get Evolution to automatically retrieve and deliver messages
via IMAP as fetchmail can. (Evolution does this only if you remember
to click the offline button while the ppp link is still active.)

Now I worry that someone will send her a link to a web site she can't
view because it contains flash or java (neither of which I have
installed). I think my wife sent her a flash link last night. I'm not
relishing learning how to install those things over a dialup
connection, so the machine may have to come back to my house for
another upgrade.  :-(
