[LINK] RFI: Email Download Failure from Local ISP

People with low threshholds for stupidity please tune out now.

Please tell me I'm a dubbo and need to try harder.  Or explain what's 
happened here (and, if you're even cleverer, why I can't quite see 
it).

I think my failure to get email this evening may be my ISP's fault.

(Or maybe Telstra's.  But that would be just *too* much of a cop-out).

If you don't love 'em you lose 'em, so I use a local ISP:

At 22:00+11 Tue 22 Jan 2008 and up to 23:00ish, fetches of mail from 
mail.apex.net.au were dropping out - Eudora said 'No response after 
120 seconds'.

The Squirrelmail/webmail alternative also wasn't working, just 
hanging, and finally displaying a message I haven't seen before (at 
the very bottom).

A search of the DNS on mail.apex.net.au delivered:
15 - postoffice.telstra.net.au. (203.50.2.186)
[Only one MX record??  What kind of fallback arrangements are in place??]
[And Apex subcontracts to Telstra for an smtp server??]
[I asked about that a few months ago, and wasn't sure that I 
understood the answer.  Maybe I should have listened more closely, or 
thought deeper?]

A traceroute of mail.apex.net.au delivered a connection that appeared 
to be inconsistent with the above.  It ended up at 203.20.62.10.

That *also* back-translates as mail.apex.net.au.

Apex resolved to 203.20.62.16
Its DNS servers were shown as:
ns1.apex.net.au		203.20.62.12
ns2.apex.net.au		203.20.62.13
[I've previously threatened to abandon them because the backup 
DNS-server is on the same subnet as the primary, in breach of the 
(advisory only) IETF RFC, i.e. the nearest thing to a standard that 
exists in Internet contexts]

I divert all of my various email-addresses to xamax.com.au, which is 
delegated to Apex.

Xamax's MX entry is:  20 - mail2.apex.net.au. (203.20.62.11)

An attempt to fetch mail from mail2.apex.net.au produces:
Server not responding. 706; Lost connection to the server.

[Am I going mad, or has Apex stuffed up its DNS entries?

[Am I a goose for delegating to an ISP who may only know marginally 
more about what they're doing than I do?]

[Declaration:  Among a few other things, I teach a Masters seminar in 
Internet and Web Infrastructure for eCommerce.  But then it's only at 
a University;  and it's not as if I'm claiming to be able to actually 
*do* things that I teach about.  'Those who can, do ...', etc. ]
