The DUL (Dial-Up List) contains more than just dial-up addresses.  It
contains all dynamically-assigned-by-an-ISP-to-"residential"-customers.
Many DSL and cable addresses are part of the DUL.

Another thing to check is the reverse DNS for your address.  Some ISPs
set up the records properly and some don't.  Some mail admins reject
connections from hosts without reverse DNS records.

I have my system set up to connect directly, except for a few domains
which I've found won't take my connection.  For those I route them
through a smarthost.
