[Dovecot] dovecot support ms-tnef mail parser?

[DongYu.Zhen]

Hello everybody,
I used iRedMail Server with dovecot-1.2.0. I used OutLook2007 send a RTF
mail and the mail can't be parsed normal.

In dovecot maildir storage the mail body appeared ,/
/

/------=_NextPart_000_0007_01CD52BC.99E1BE10
Content-Type: application/ms-tnef;
        name="winmail.dat"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
        filename="winmail.dat"/

How to parse ms-tnef mail by dovecot?
Thank you.
