That is easy.
Have your users connect to the submission port
Yes Wietse, I've considered this simple and clean option, but
we're a hosting company and the costumers are to lazy to understand
and accept an approach like this.
Force them by making 587 the ONLY way to send mail. Tell them it's
for security reasons and make sure you enforce it.
That's all fine and well for small sites, but hardly a solution for
larger environments where such draconian measures are impractical. A
more reasonable solution is for the OP to push users toward submission
via 587, and in the (very long) meantime, find other ways to bifurcate
SASL vs. non-SASL traffic on port 25.
