There was just a sub-thread about this, but with a much less obvious
subject. Clam (at least) *does* now unpack MIME messages, so not
using demime will work, in general.

But there were comments about Clam's MIME parser being younger and
potentially more fragile that Exiscan's, so there may still be some
reason to prefer demime.

Correct.

Not so far. decode in the MIME ACL does not cause malware in the
DATA ACL to pass individual message parts to the scanner. And IIRC,
there are other scanners listed in the exiscan/4.50 docs as not
unpacking MIME containers.
