Hi Jacek,
Strange, if anything I get the opposite problem - I often get the same mail
twice!! No idea why.
Regarding the list being quieter, I would suggest that's because it has
become dominated by mails relating to much lower frequencies of little
practical use to most of us.
Vy 73,

Thanks Alan,
Yes i'm aware that many people don't know how smtp works, and that ISPs
break it badly while trying to fight spam (btw this is why i run my smtp
servers, some of the things isps do are totally unacceptable and
uncontrollable by the end user).
This is why i asked for info from people that are getting bounces, and
that didn't have problems previously but now have them (maybe i didn't
write this clearly enough). The list has been quieter lately. I know of a
user that started to have problems recently, and bounces related to tls
problems (probably related to people being more keen on upgrading openssl
recently).

Jacek, there are a number of possible reasons why messages do not "seem"
to go through the mailing list. I write seem in quotes because many do
not understand the route the messages take. Also I remind that not
receiving your posting back is not proof it did not arrive or that other
members did not get it. The situation is massively complicated by the
various ISP servers apply their own rules to try to reduce spam. Bounces
are generally not received from this group I believe. And undelivered
message report is also dumped. One reason is the obvious one of the ease
of producing a "ping-pong" effect.
There is little problem with UK originated messages though one or two
even have problems here. The most often reported losses are from non-UK
originators. In many cases we in the UK see the distribution but the
originator does not get his posting back. This is aften a function of the
ISP who it would seem regards messages to the originator are likely to be
spam. I have several cases of this happening with specific ISPs on Yahoo
Groups. Some globe-trotting users like Laurence KL7L were unable to post
from China. We think this was route blacklisting but having no access to
admin we have no way of confirming.
All I can say is use text (not HTML) which can confuse the parser, keep
messages and particularly attachments below about 200kB (I can't now
remember the actual limit....it may be more than this but is certainly
not exceeding 500kB).
Do not leave the subject line blank if there is an attachment, because
this trips up the parser.
Make sure you use the exact posting address you subscribed with. I
believe gmail and googlemail are regarded as the same but they are two
separate addresses to an ancient list-server like this. If the problem
continues I suggest re-subscribing with a different address.
Now there have been significant delays reported on several lists in the
last few days. Yahoo has be delaying occasional messages 3 or 4 days.
This can be due to congestion during DDoS attacks.
As I said I have no admin access to this server but if the member having
problems would like to copy me in on postings to the group, I can check
arrival at least.

Subject: LF: problems with mails to the list?
does anyone have problems sending mail to this list? if so could you
please send me the bounced message that you got (off list of course)?
one of the members of this list wrote me that he has problems having his
emails accepted since a few days because of problems negotiating tls (so
far we don't know if it's a problem with this list's email servers, or
his provider's email servers. both seem to do tls 1.2 without problem).
maybe this is the reason why this list has less posts lately (summer
propagation on lf/mf might be another reason).
btw i have never had any problems with emails bouncing or being delayed,
but some people reported it in the past.
