GGs,

I haven't seen any evidence of missing messages to my account (gmail) or on
the Archive (my personal server), which makes me think this is likely an
issue of filtering by your mail provider, either messages winding up in
Spam or outright rejected. Typically, rejections are bounced back to the
sender (groups.io) and you'd get a message if that happened warning you
that messages are bouncing from your account. I can see the list of those
currently "boucing" and none of the people responding to this thread are on
that list.

The email system is very resiliant to distruptions with a mail server
trying many times to get through to a recipient before finally giving up
and bouncing the message back. Since those reporting issues aren't on the
bounce list, this implies that the mail server attempted delivery, your
mail server accepted the messages, and the message was lost at some point
after that. Once a mail server gets the status 250 code (message accepted)
from the recipient's server, it's out of the picture.

Mailing lists are hard because the individual messages are coming from a
variety of different email addresses, and the sending server (groups.io)
doesn't match the original sender's domain, so these messages look
suspicious. For example, this message will likely have a From header of <
cswingle@g...>, but if you look inside the headers, the last server in
the message chain will have a Received header of "groups.io", not "gmail.com".
There are additional headers intended to make it clear that the mssage is
part of a list and this discrepancy is to be expected, but of course, those
can be spoofed by spammers as well.

Anyway, I don't have any easy solutions, but I'm pretty sure this is
happening within your mail provider's service. It would be nice to think
they would consider you a valuable customer and would respond to complaints
about the service you are receiving from them. If you can find a missing
message in the Archive, I might be able to retrieve the headers from that
message and this could be useful information to pass on to your provider.

And yes, please trim your replies, and reply below the statements you are
responding to. It takes a bit of work, but it's good for the Archives and
it's easier to understand what you are trying to say.

Cheers,

ListMom, Chris
