Luckily here a couple of shops remain, even for clothes and
electronics (mostly household).  It is much uglier a bit further
away, most smaller villages to not even have a bank or even
a bakery no more; some have (also new) so-called "Tante Emma
Laden" (Aunt Emma Shop) which offer a bit.  Situation is bad for
elder people on the land.  Even very bad as younger doctors do not
go there, and we have had a political movement on Germany over
twenty years ago to do something against this trend.
Unfortunately then there was a government change, but it surely
would have failed even without that.  It is just the western world
.. and/but not only that and there, of course.  (Though it is
and was mostly the western world which puts pressure due to its
way of doing things; others can do nothing but follow due to
economic pressure, sooner or later.  But that leads much too far.)

Well.  For one: i try to avoid too much consumation at first.
Most of it is due to brain aka character failures, aka
"replacement acts" (sorry, my english) to fill a void.  Now
whereas i grant there is nothing but void, that void is possibly
full of light.  That is of course religious, philosophical, etc.
Take Alexander Solschenizyn: a hero, then in the Bolschewik Gulag,
and when he came back all that he wanted was some bred, sauerkraut
and a bottle of Milk a day.  (Said Schostakowisch where he lived.)
Eh.  I think that christian guy also went to the desert and came
back saying such before they nailed that sausage somewhere.

That is that.  No to it actually is yes.  (Let alone that totally
responseless western way of doing things, or do you buy fairphone
and such.  Cheap buying, expensive selling.  Destroys life on
earth.  They knew that over 150 years ago btw.!  And the Club of
Rome gave a picture in 1972 that we still do not look at.  No.)

But sigh before i start praying.
Regarding electronics we have a good one in Darmstadt for many
decades, Zimmermann Electronic.  And some good (other) computer
shops, too.  But this is a privileged and "rich" area here, so,
well, yes, i can understand this.  Of course i do.

Then again, if it has not to happen from day to day, one could
drive in the next bigger city and buy there, have a coffee or tea
(or a smoke dependent who and where you are), and an afternoon in
the city, and then go back, on the next Saturday or so.  Or stay
longer, for some Saturday night.

Yes.  Permanently, you initiate it once, and then it happens
periodically.

Ah -- you know the bank was like that two decades ago.  Then they
did something interesting, shall you ever have read the book "The
Money Exchangers" or what its name way, Arthur Hailey i think hmm.
So the fun comes only if you know the book.
They extended the room and split it 50:50 into a part full of
"robots" and some places where human sit.  A moving glass wall
locks the human part away out of the work hours.  The robotic part
does no longer have a trashbin even, i think someone made some
fire there (and the cameras did not help).
So you mostly interact with the robots here.

You know.  Family businesses

The timeout happened with the connection idle after "." for 20
seconds.  Perhaps the remote client was caching the connection for
reuse.  While Postfix connection caching is more "polite".

Mind you, I think you might have a non-default timeout setting, the
default smtpd(8) timeout is 300s.

according to my logs google mailservers close connection to my SMTP about 30

Looks like you have lowered smtpd_timeout to 20 seconds, in which case smtp 
server closes connection sooner.


Or, your machins is under stress and has timeout 20 seconds in this case. 
the default:


smtpd_timeout = ${stress?{10}:{300}}s

Yes, the broader the question, the longer the answer.  On the other
hand, understanding Postfix address rewriting is essential knowledge
for using Postfix to its full potential.

When asking a timing related question, it would be helpful if you
did not delete the timing related onfo from the logs.

[pfx] timeout after END-OF-MESSAGE

2023-03-20 Thread Fourhundred Thecat via Postfix-users

Hello,

I occasionally see timeout after END-OF-MESSAGE in my logs:

  timeout after END-OF-MESSAGE from mail-lf1-f49.google.com[209.85.167.49]
  disconnect from mail-lf1-f49.google.com[209.85.167.49] ehlo=2
starttls=1 mail=1 rcpt=1 bdat=1 commands=6

Is this misbehaving client, or might this be some misconfiguration on my
side?

I have pasted postconf -n output here:

Thanks Viktor.  I tried the debug approach before posting.  That's why I made 
the request.  The web page requires a lot of parsing too though.
