This field is added by the ezmlm software that is used to manage our
mailing lists.

More things in heaven and earth, Horatio?
From the procmailex manpage:
If you are subscribed to several mailinglists and people cross-post to
some of them, you usually receive several duplicate mails (one from
every list). The following simple recipe eliminates duplicate mails.
It tells formail to keep an 8KB cache file in which it will store the
Message-IDs of the most recent mails you received. Since Message-IDs
are guaranteed to be unique for every new mail, they are ideally suited
to weed out duplicate mails. Simply put the following recipe at the
top of your rcfile, and no duplicate mail will get past it.
:0 Wh: msgid.lock
| formail -D 8192 msgid.cache
