We do not. We inadvertently did and it wasted a lot of our time when
our customers would periodically send mail that we would tag as spam,
since they would call us and complain. The arguments that their mail
would also have been tagged as spam by their recipient's mailserver
mostly fell on deaf ears.
So instead we launched a campaign to convert all users to auth-smtp
using strong passwords and have mostly succeeded. The campaign was
helped by gradually erecting port 25 blocks in strategic areas of our
network.
Note that a password of 6 chars with 1-2 of them special chars is
apparently considered very strong by spambots.

However, a couple of issues recently with spambots and SMTP AUTH with
weak passwords has me reconsidering that stance.
Is anyone here currently scanning their outgoing mail with SA? Good
results? Bad results?
