I'm having a lot of problems with GMail delivery due to lack of "one-click

See the footer of this message which contains
To unsubscribe send an email to mailman-users-le...@mailman3.org
This is produced by
To unsubscribe send an email to ${short_listname}-leave@${domain}
in the template which is also in the default template. This seems
sufficient for Google, as I don't see mail bounced for this reason.
You might try adding a link to Postorius. You can't really link to an
immediate unsubscribe as that requires the user be logged in (and the
user may not even have an account) and it also required POST data, but
for Mailman >= 3.3.10, you could add
To unsubscribe send an email to ${short_listname}-leave@${domain}
or go to $mailinglist_url
This requires the domain have a base_url set. See
<https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/rest/docs/domains.html#domain-urls>
and this is not yet exposed in Postorius. See
https://gitlab.com/mailman/postorius/-/issues/594
In particular, there is an issue with the fact that Google ignores dots in email addresses. So I have many
(MANY!) subscribers who try to use the List-Unsubscribe header target, but because they are subscribed as
"idiotsubscri...@gmail.com" rather than "idiot.subscri...@gmail.com" (which they have
since changed their sender to) they get a reject that they are not subscribed. These people are also far too
unobservant to read the footer of every message that reads "You are subscribed as
idiotsubscri...@gmail.com".
Is there any way to provide personalized List-Unsubscribe header links, or have
Mailman ignore dots in gmail.com addresses... or... anything? I'm finding
reported spam percentages in the Google Postmaster Dashboard exceeding 0.1%,
which causes massive delivery blocking to GMail-based subscribers.
The List-Unsubscribe: header is added in the handler pipeline by
mailman/handlers/rfc_2369.py. At his point in the process the message is
still generic so the header can't be personalized. The
mailman/handlers/decorate.py handler can add personalized content so
could modify the List-Unsubscribe: header to add the recipient's email
address except at least at present this won't work because emails to
listname-leave or listname-request with a leave or unsubscribe command
currently only look at the sender of the email for the address to
unsubscribe.
