Or, if you are filtering/sorting incoming email through procmail(1),
the References: header will contain a same ID for duplicate emails,
(which is derived from the Message-ID: header.)

Something like:

    :0 Wh :msgid.lock
    | formail -D $idcache_size msgid.cache

in ~/.procmailrc will eliminate a duplicate email.
