I've been using ssl-only-settings since 2004 on our mail servers and I
can tell you there are zero mainstream mail clients that don't support
any kind of ssl. Since a very long time.
The only things we ever ran into not supporting our setups were really
weird pieces of software. None of then normal mail clients, it's more
the "embedded device that can use smtp to send a mail" kind of software.

The problem you're probably facing is that up until recently, many mail
clients didn't enable ssl per default. We managed to instruct all our
customers with all mail clients over the years to enable ssl.

Wrong. Outlook 2007 supports SSL. Here's a doc:

I don't know Entourage, but a quick google search turns up this:
So I think it also supports SSL.

Sadly, very often the problem with crypto is that people keep telling
"there are clients that don't support X" based on improper info, so I
want to make it clear again: Problems with non-ssl-speaking mail
software are really really rare. It's a matter of the right
documentation how to enable it.

One more point: "Deutsche Telekom", which is the no 1 provider in
Germany recently switched to ssl-only-email. They have a lot of
non-techie-customers. Probably more than anyone else in Germany. If
they can do that it can't be too much of an issue.
