#364 2.11 alpha1 triple sub/unsub message

[Mariano Absatz]

Some subscribe and unsubscribe messages (I think
everyone but the first for a given address) from
http://mojo.skazat.com/cgi-bin/dada/mail.cgi/ are
issued 3 times.

The messages have actually different Date: and
Message-Id: headers (so the problem seems more
dada-related than mailserver related).

Sample repeated message headers:
