... and immediately I have been able to verify a bunch of
domains/servers which won't get thru when incoming connection
has ECN. I tested all of these with Linux running ECN, and
Solaris 2.6 without ECN. When Solaris got connection, and
ECN-Linux didn't, domain and its server got listed.
Amazing share of these troubled destination systems run some
firewall which thinks it is cool to fuck SMTP protocol.
(I mean obscuring responses given by the remote system,
frobbing incoming protocol if some particular detail doesn't
please the rules it presumes to play with, etc..)
I am contemplating to periodically turn off the ECN bit to
let email out, but DaveM has veto there.
This list is NOT exhaustive of domains with problems, it
primarily lists only those who are subscribers of linux-kernel,
and thus accumulated (al lot) more than 1 email with "connection
timed out" status into vger's queue.

And back in January he said he'd be doing it in February. The kernel list FAQ has stated this right at the top, in big, bright red letters. Yesterday, after I saw Dave's announcement, I updated the FAQ to reflect that we're now running ECN. People have had plenty of warning. Think of it as a bonus that it didn't happen back in February. They've had an extra 3 months to sort something out. I note with disgust the number of places which should know better, but still haven't fixed their kit. Most appalling was missionalcriticallinux.com. Shame! Sure, Dave is being bloody-minded, but that's the only way we'll see people get off their fat, lazy asses and fix their broken systems. In fact, hopefully he's still in a dark mood, and he may take up the suggestion to bounce mails of the following type: - MIME encoded - HTML encoded - quoted printables (those stupid "=20" things are particuarly hard to read).

Bounces to where ? The bounces ARE in MIME, but frobbing them into HTML is ... That would involve my dead body, which I am not keen on supplying. And for that matter, people who you do want to punish do run MUAs, which happily open up everything -- except these bounce reports VGER generates.

The "we'll turn it on in February" warning is worth NOTHING in this situation: February comes and goes. March comes and goes. Everybody who read the warning will think: Ok, so I must be fine. A warning of the form: "ECN will go on as soon as this message clears the queues" would've been useful, as thousands (hundreds?) suddenly get nothing anymore.

And since some people send to the list without being subscribed (or, like me, have duplicate filtering), they'll never see that their message was mangled as it passed through the list. Nope, a bounce is better. If you're going to do these things, feedback is essential. The bounce isn't meant to offend the sender, it's designed to let them know what's happening. Regards, Richard....

The only GOOD time to bounce is at SMTP reception into VGER, not latter. It doesn't have facilities to do all what Majordomo taboo filters do now. (Just because I have been lazy and haven't done any such content filters for vger.) With ECN on, emailed bounce messages won't (necessarily) make it to the sender at all. Majordomo's filter bounces the message to be approved by list owner -- who usually uses the 'D' key to my knowledge. > Regards, > > Richard.... > Permanent: rgooch@atnf.csiro.au > Current: rgooch@ras.ucalgary.ca /Matti Aarnio ^ permalink raw reply [flat|nested] 25+ messages in thread

MIME is no encoding, but a way to declare mail contents and encode binary data. You need not use it on mail you send. HTML is no encoding. (No doubt it's usually sent by people without A Clue[tm] or being ruthless.) quoted-printable is an encoding, and it's probably around for ten years now. I can send base64 if you like that better, but then, even more people will cry, while others don't even notice. Gnus 5.8 + Emacs, mutt, Netscape Communicator are three packages which deal with MIME-"enhanced" mail. Plus, people which use any characters beyond ASCII have no real choice but to use MIME; if they have MTAs in between that don't talk ESMTP/8BITMIME, then quoted-printable is what happens. Use emil, metamail or such if you want to keep your mailer. -- Matthias Andree ^ permalink raw reply [flat|nested] 25+ messages in thread

I'd suggest something like: Final Warning. ECN is being turned on NOW. If your firewall doesn't support ECN, this will be the last message that gets through to you from us. Such a message will have the interesting characteristic of being the last message received. This will make it obvious why no further messages are arriving.

I agree with this line of thinking. The various academics studying
geology have been warning California about "The Big One" for years now,
and no one seems to care anymore.
I don't think anyone's being lazy and I certainly don't have the
information to comment on the size of their butts. So I'd rather just
assume they were working very hard on other things (like getting TPC-H
benchmarks to run!)
