Does everyone who is authorized to use this server for outbound relay
use authentication? That would be best, you don't have to worry
about what host they are on.

Sounds like you just need to add an accept stanza to handle
authorized users sending to spamsoap_domains directly. If they all
authenticate, it can be as simple as:

   accept domains    = +spamsoap_domains
          authenticated = *


Put this above the existing accept stanza (because of it's endpass).
