It can be per-recipient since 2.3.0. See 2.3.0 release notes under
NEW FEATURES. (but one should be using 2.3.3 nevertheless)

I must admit I haven't tried the above, and I expect there might be
unexpected interactions between MIME type, file name and short file types,
as each node in a MIME tree can have each one of these three attributes,
but need not have them. The program does work according to specs,
it's just the usability of this approach which needs to be tried out.

If it would turn out you need more complex rules, there is always a
choice of using the more complex $banned_namepath_re instead of
the easier to comprehend but less expressive $banned_filename_re.
