Hello,
RTFM, please.
The Postfix SASL_README file says:
Communication between the Postfix SMTP server and Dovecot
SASL happens via a UNIX-domain socket.
Support for inet: is NOT DOCUMENTED. It may disappear any time.
There is no promise nowhere that this actually works.
You use NOT DOCUMENTED settings at your own risk. I have no plans
to I write warnings for settings that are NOT DOCUMENTED.

this is true. may be i stated the question in an inaccurate way and would
like to turn this message into a feature request so it gets an official
feature next releases.
auth-service on tcp-socket was added to dovecot last november, the docs are
updated these days i read.
http://dovecot.org/list/dovecot/2011-March/057780.html
i think in some cases it is not recommend to have a local dovecot installed
and more valuable to ask a central installation by tcp.
so my suggestion to make this a safe feature.
Thanks,
Hajo
