[exim] Different configuration for different ports

Hi, all!

We'd like to configure the port 587 for incoming E-Mail of our customer (we
have some customers from AOL and AOL blocks port 25).
We'd like to have the port 587 just accepts query with an authentication
(SASL, Pop-Before-SMTP).

Now the question: is it possibile to configure Exim to use different
configuration for different port or have I to have two different exim daemons
with the different configuration?

Thanks a lot in advance!
