This is indexed under "size limit" and "message size limit".

Use a system filter with a command something like this:
if
$h_content-type: does not match "^$|doc|xls|txt"
then
fail "Silly security policy requires this message to be rejected."
endif
(The ^$ at the start matches an empty string - what you'll get if there
isn't a Content-Type: header at all.)

(A) Use a domainlist router to give a list of hosts.
or
(B) Use fallback_hosts.

Set up appropriate rewriting rules in the rewrite section of the
configuration. For example:
xx@??? aa@???
Not very difficult!
