In order to scan for Troj/Sefex-A it is essential to have
    Mime: 0
This is also according to a support answer from Sophos.
Als the Mime option belongs to the GrpInternet and you want to have
    GrpInternet: 1
it is essential that you explicitely set Mime to 0, later.
It is also important that all the Grp* options are set prior to any
other option, so keep those at the top of your sophie.savi file.

"Mime enables decoding and scanning inside a MIME encoded message block".
IMHO the broken MIME mimic of Troj/Sefex-A causes the SAVI to
incorrectly handle the file that's why you can detect the virus with
sweep -mime either.
