cleanup(8) man page

[Patrick Lamaiziere]

Hello,

I think that the description in this man page is confusing since cleanup
does not *always* insert missing headers (message-id etc).

The cleanup(8) daemon always performs the following transformations:

       o      Insert missing  message  headers:  (Resent-)  From:,
       To:,  Mes- sage-Id:, and Date:.

We hit this here :)

Thanks, Best regards.
