Re: f-prot not catching mimail ?

As previously noted, the problem here seems to be with the f-prot
binary, not the actual virus signatures/definitions.  Try upgrading
the f-prot package, and it'll probably work fine.

I cannot see anything "special" in the MIME structure of Mimail that would
cause f-prot to miss the ZIP attachment (or maybe it is the structure of
the ZIP that f-prot cannot unpack?).

I was told its the encoding scheme in the .html file thats the problem. 
Currently the scanner does not support that type of encoding.

It seems to me that the HTML contains the binary EXE without any encoding:

$ cat -v message.html | fold | head -5
MIME-Version: 1.0
Content-Location:File://foo.exe
Content-Transfer-Encoding: binary

MZM-^P^@^C^@^@^@^D^@^@^@M-^?M-^?^@^@M-8^@^@^@^@^@^@^@@^@^@^@^@^@^@^@^@^@^@^@^@^@

Regardless, f-prot should list the ZIP attachment, and the files contained
within the ZIP ...
