Testing (sorry)

[Peter J. Holzer]

[Replying to the list *and* Grant]

Today I noticed that nothing I've posted to python-list in past 3
weeks has shown up on the list.

January 29th, AFAICS. And end of december before that.

I don't know how to troubleshoot this other than sending test
messages. Obviously, if this shows up on the list, then I've gotten
it to work...

This did show up and 3 other test messages with very similar text
as well.

Also there was a whole flurry of almost but not quite identical messages
from you in the "nan" thread.

But posts to the list still seemed to vanish into the ether while
emails from both accounts reached other destinations without delay,
During this process a number of posts from other users did appear in
the list archive and at at _one_ of the two e-mail addresses which I
had subscribed.
But no sign of any of my posts.
About 24 hours later, all of my posts (and the confirmation e-mails)
all showed up in a burst at the same time on two different unrelated
e-mail accounts.
I still have no clue what was going on...

Looking at the email-headers, there are sometimes considerable delays
between messages submitted to the List-reflector, and their outward
transmission (to me).

Interestingly, there's something strange about the queuing. Instead of
FIFO it seems some messages arrive ahead of others, ie out-of-sequence.
(wonder if explained by submission via email or Usenet?)

I've noted long delays too. Perhaps (also) to do with time-of-day?

Always feel slightly embarrassed if 'repeat' an answer* that someone
else had previously submitted, eg __new__ thread and @MRAB. However, if
the reflector 'holds onto' the earlier message, then how should I/anyone
know?

* yes, repetition improves learning, slightly different words may help
comprehension; but doubt I can express anything better than the
aforementioned does/did/can.

I can't explain the delays, but will note that the gate-news program on the
server runs every 5 minutes via cron. There are multiple moving parts in
the overall system. You'll probably get a more useful answer from
***@python.org.

Sometimes a post of mine will not show up for hours or even half a day.
They are all addressed directly to the list. Sometimes my email
provider sends me a notice that the message bounced. Those notices say
that the address wasn't available when the transmission was tried.

I guess that in future I'll wait a couple days before I assume
something is broken.

Here is a typical bounce message that I get:

<python-***@python.org>: host mail.python.org[188.166.95.178] said:
450-4.3.2
Service currently unavailable 450 4.3.2

Some time after I get one of these messages I re-send the post. Usually
it gets through then.

Looks kinda like greylisting to me. I'm pretty sure that's one of the tool
in the mail.python.org chain.

This is a *temporary* error. Your provider's server should retry
delivering the message for a decent amount of time (3 to 7 days is
customary).

Your provider's server may send you a notification that the mail cannot
currently be delivered and that it will keep trying. Such notifications
are usually sent after a much shorter period (a few hours).
