    Bon j'ai fini par rendre la regle un poil plus efficace, a savoir que sous linux j'ai jamais besoin d'executables windows, et que les zip c gentil mais pas qd ca ressemble au MyDoom:
    # Piege a worm con qui se fout sous la forme d'un exe win32
    :0 BD:
     * name=".*\.(scr|bat|pif|cmd|exe)"
     "${MAIL_DIR}/junk"
    # le piege a MyDoom proprement dit
    :0 BHD :
     * -700^0
     * 100^0 > 30000
     * 100^0 < 36000
     * 100^0 ^Subject: (Mail Delivery System|Hi|Hello|hello|Test|test|Status)
     * 100^0 ^X-Priority: 3
     * 100^0 ^X-MSMail-Priority: Normal
     * 100^0 Content-Type: text/plain;
     * 100^0 charset="Windows-1252"
     * 100^0 Content-Type: multipart/mixed;
     * 100^0 ^The message cannot be represented in 7-bit ASCII encoding and has been sent as a binary attachment\.
     * 100^0 ^The message contains Unicode characters and has been sent as a binary attachment\.
     * 100^0 ^Mail transaction failed. Partial message is available\.
    # just test the zip extension as usual extensions get trapped by the
    # "dumb worms" rule
     * 100^0 name=".*\.zip"
     "${MAIL_DIR}/junk"
    
    Enjoy
