Mail loop at a2000.nl (was Re: [HACKERS] PATCH for pgconnection.h)

And look at the dates!

This morning I sent a polite note to postmaster@cable.a2000.nl, warning
them that they've got a problem with mail looping. It promptly bounced
back with

postmaster@cable.a2000.nl:
SMTP error from remote mailer after RCPT TO:
<postmaster@cable.a2000.nl>:
host hardy-1.a2000.nl [192.168.17.13]:
550 Invalid recipient <postmaster@cable.a2000.nl>

I've also tried to send to postmaster@hardy-1.a2000.nl.
Result: unknown host :-)

But the CC to Z.Nijmeyers@cable.a2000.nl didn't bounce. Maybe
he'll receive it and can forward it in HARDCOPY to his
pEstmaster.

(Sending to postmaster@a2000.nl instead probably won't help, since it
MX's to the same machines.)

I conclude that a2000.nl is run by a bunch of idiots who can't read
RFCs, let alone operate a mail server competently. I expect that
we will continue to get blessed with regurgitated messages until Marc
pulls any a2000.nl addresses from the mailing lists :-(

Looks like someone's mailer reinjected this one.

Yes, along with five others that were also about two weeks old.
I recall having noticed several other such incidents in the recent
past, all bearing headers that indicate the retransmitted messages
originally went from the mail list to one <Z.Nijmeyers@cable.a2000.nl>.

Start of reinjection of this one (note date):

Could be that they're idiots, if so I hope they can find some competent people
to help them out there. They're the TV cable operators for Amsterdam and surroundings
and have probably about half a million houses connected to their network.
Since about a year and a half (I guess) they're into internet over cable modems, and
actually the bandwidth they deliver is pretty impressive (especially if you're
used to 28k8 modems ;)

I'm really sorry that my ISP is doing wonderful :-) things to it's

they are a bunch of idiots and complaining doesn't help a bit, in the past
couple of weeks everyone in amsterdam who has cable internet, has had
extreme trouble with email.

we will continue to get blessed with regurgitated messages until Marc

If the problem persists with a2000 messages looping back please let me know
and I will unsubscribe from the list and resubscribe using another email
address
