[Dovecot] SASL from remote server

[Daniel L. Miller]

Is there a way, using Dovecot and Postfix, to use SASL from a remote 
server?  Since it appears the communication uses Unix sockets, does this 
mean it is restricted to local services only?

I have a two-server configuration, where my firewall also runs the mail 
gateway/filter (Postfix + ASSP).  My internal server has Postfix + 
Dovecot.  Right now I have my internal server configured to use Dovecot 
SASL, but the external server is still using the Courier authdaemon 
against the LDAP database.
