That much, I seem to have... It asked for a password,
then contentedly showed an empty Inbox.

Will do.

Remind me what setting(s) in main.cf need to be in
what condition to avoid open relay. (I don't want
to assume anything about defaults, nor to assume
anything about my understanding of all the pages
I've read.)

Here's a place that I might be messing up, due to
lack of understanding of what goes where. I know
it's really simple, but when you've never had it
actually work before, you can be doing something
really 'obvious' and dumb without realizing.

Obviously, I've got basic internet connection
working, so I've put my ISP's primary and
secondary server IPs in the right places...
As for mail-related stuff, in particular:
I'm kevinmcl-รข-magma.ca (my ISP is magma.ca and
I think I'm fooling harvest bots by writing my
e-mail address that way... hah...).
Their mail server (both incoming and outgoing)
is "mail.magma.ca".
I've filled those items in where it seemed
appropriate in configuration, which was later,
in fetchmailconf, but I'm summarizing here.

On my own network, there is no DNS server.
I'm using a LinkSys router that is 192.168.1.1.
My PC-that-wants-to-be-mail-server is (say)
192.168.1.91 (static) and thinks of itself
as hostname "junkbox".
Anyplace that I've been prompted for an in-house
"domain" or workgroup (such as when setting up
Samba) I've said "OURHOUSE".

One of the many things I'm not clear about is
where (in all the various setups/configs) I'm
allowed/supposed to use the bogus 'domain'
"OURHOUSE", as opposed to some real domain.

I also avoid configuring things like masquerading
and any rewriting of addresses, since I'm not
clear on what goes where and don't need to break
something else while the utter basic stuff isn't
working.

I'm guessing that with no in-house DNS, I don't
worry about publishing MX record...? Or have
I misunderstood?

Outbound, I'll use the ISP's smart-host service
until I've had the incoming path working for a while.

Never having had the simple chain working before,
I don't even know how to recognize that one or
another component is working separately. Or, I
didn't until you described how to fire a testmail
into Cyrus, and suggested working from Cyrus backwards.
Suddenly a tiny part makes more sense.

"Tuning" he says. TUNING! Hah! In my dreams. :-)

Anyway, thanks a bunch. I'm printing out your message,
and heading home for a couple of weeks of "vacation" -
also known as anguish and frustration in front of
the Linux box, interspersed with episodes of yard work
and house maintenance. Woohoo.
