punt-21 seems to want to keep talking to my mail server every ten
minutes, like this:
NOQUEUE: Null connection from punt-21.mail.demon.net [194.217.242.6]
I assume it's all related to today's mail shenanigans...

Yes - please ignore this for the present time. As noted in status@gate
work is taking place to find and remove the zero length emails that
are causing this. They were created by email in transit internally when
the outage occured.

Can we settle on the pragmatic lost as in "not delivered yet"?

Yes but spam tends to turn up multiple times.
My truncated email is I believe still missing in transit presumed in the
bit bucket 24 hours later. See "strange email" thread.
Does this mean that Demon's in-transit email is stored on a volatile
storage medium, rather than committed to disk, before forwarding it on?

Heh - be careful of where you're going with this! :D
If there was an outage which caused the mailserver to die
catastrophically and dump it's core - the disks will be in an
"indeterminate" state.
That leaves them to be FSCK'd on reboot, which could take a lot of
time.
Then, you can recover from the error *provided* you are using a
journaled filesystem - and the data and journal are intact, too, or
can be reconstructed trivially.
To absolutely guarantee that, you'd need multiple machines running in
synch - and that's assuming a non-widescale non-redundant fatal
defect, like a faulty backplane in one machine. (Why do Compaq/HP and
Dell and Sun all make machines with multiple power supplies and yet
one common power board?) If the room got totalled, this is all
academic.
Email often sounds a trivial application, until one actually totals up
the bandwidth, capacity, and latency of the machines that are
required. Serving webpages is a piece of cake compared.
That's not defending Demon, who should come up with the goods we pay
them for, in an ideal world. But, at the moment, I'm satisfied that
they are doing their best to improve it. Remember that Demon is a lot
older than most ISP's, and there is probably a legacy equipment factor
to take into account, too.
I'd love to know Demon's hardware models, both old and new, for their
Email engines. How about it? When's the guided tour? ;)

You're kidding? I used to work for one of their dealers.
The Xi - a sexy black machine twenty years before Dell made them
popular again. HDD size a smidgen smaller at 10Mb, and at around 4K a
little more expensive for the discerning punter.
Anyone remember the F1 "home machine"? ;)

My recollection is:
Demon's gateway was a hefty Apricot i486 server, (the *first* 486 server
model on the market), running SCO Unix (Xenix?) and MorningStar PPP.

I've still got a black Xi, somewhere in the loft. AFAIR 9" green
monitor (beige case), Network card (token ring?), extra RAM and a
single floppy.

*Not* the FT? (Later renamed the FTs)
The one we called, the "Fridge" because it was the first real
datacentre PC, with inbuilt UPS and lots of internal storage.
Not a lot of people know that the front control panel could make the
machine play "God save the Queen" and the "Blue Danube", amongst other
things... (Hold down Button 1 & 5, those of you who have one still
alive!)
The inbuilt security system made far more noise than a car alarm, and
was unapproachable if it got set off in a room. Lucky we had those IR
transponder blippers to switch them off at a distance!
My favourite memory is of visiting Apricot in Birmingham in my first
week, and meeting Pete White, the UNIX guru there. I asked him why the
FT had such a big gap between the front armoured door protecting the
drive bays, and the bays themselves.
At which point he turned around, and opened one he had behind him, to
reveal four cans of Heinekin neatly stacked behind the door, chilled
to perfection by the brutes efficient cooling system.
Apparently, the gap was part of the design spec for thirsty techies to
have somewhere to hide their emergency refreshment in the datacentre.
You just don't get that consideration nowadays with Proliants...

I hear you can get a very good price for them on Ebay - either fully
working or as spares for other peoples museums.

I remember working on one of those black jobs! Then we had a new one
which was beige and had some IR keyboard thing with a fibre optic cable
in between the two. As I remember the AA batteries were always flat when
I came to use it! Oh god I was 17 then. Eeeeeek

Indeed - the "light pipe" - which was needed if you wanted to run two
machines together in the same office, the KB's and mice being infrared
and liable to crosstalk!

Cliff certainly used SCO Unix, but this was considerably later than the
Xenix days - He asked me to port the POP server, but I wanted too much
money :-)
