Hello everyone,

Starting novembre 1rst, we will be removing the "Sender" field which is
automatically added to any mailing list, this should take a couple of days to
happen. This is a legacy from the majordomo time which we carried over from
mailman and now to mlmmj.  This has been replaced in 2001 by RFC 2919 aka
List-ID.  All of our mailing lists have respected this for some time now. The
most important reason for deprecating it, depending on how the initial mail was
crafted, we can end up with mails carrying 2 Sender field which leads to them
being marked as spam.

Please check that your filters have been migrated to using List-ID.

RFC 2919 says a List-ID header is in the following form:

"List-ID:" [phrase] "<" list-id ">" CRLF

I know some of you have made filters on List-ID on the full " [phrase] "<"
list-id ">" part

This is a bad habit, please make sure that you only filter on "list-id" part as
the phrase can change (fix typo, improve description etc), but the list-id part
is guaranteed to remain the same.

Best regards,
Bapt
