MIMEDefang would be a powerful point of access, but it's not very
user-accessible when you need to make changes. Mail sorting is IMO best
done purely on delivery with procmail, sieve, or some other similar
system that runs on per-user final delivery.
Why add new flags to a message with MIMEDefang? I'd imagine that
whatever system cPanel uses, you should be able to set up suitable
filters directly off the original information rather than do all the
extra work adding reformatted duplicate information.

"/usr/bin/sendmail" is considered a generic interface for local programs
to inject mail into the local mail system, whatever MTA is actually in
use. It's generally a symlink to the MTA-specific version.

No. MIMEDefang requires an MTA that supports the "milter" mail
filtering interface, which Exim doesn't support last I checked. To my
knowledge only sendmail (which originated the interface) and Postfix
support milters.
