That's up to you (or better your mimedefang-filter); you can setup MD to 
scan the message awhole, each part individually (or both), you can unpack 
archives and scan its content manually (unless your virus scanner does not 
do it itself or your filter knows more archive formats).

There is no "depth" limit in MD, however, you can limit the number of MIME 
parts, the message may contain.

BTW: If the attachments are sent via an archive, or Exchange-style MS-TNEF 
(which are archives, too), MD will see them as one single MIME part you 
have to unpack and scan yourself.
