Not too different.  My server uses a less convoluted version of this
(domain.com/user).

You can have per-user preferences and you can have scanning at the SMTP
session.  Doing both at once can be tricky.  For example, if you have an
email being sent to user1 and user2, whose preferences do you use?

Generally, if you are doing scanning during SMTP, you use a site-wide
setup.  If you want per-user preferences, you scan on delivery.  Of
course, if you have the horsepower, you can do both.  Use a conservative
site-wide setup to scan and reject obvious spam at SMTP and then use the
per-user setup to scan and flag or quarantine the rest.
