Milter-greylist

I am using a semi-open source mailserver called scalix
(http://scalix.com).  I went this route because my users had to have
the 'rich' Outlook experience, and Scalix can mimic an Exchange server
for free.

Anyways, I am trying the milter, and I see these in maillog:

skipping greylist because address 127.0.0.1 is whitelisted
X-Greylist: Sender IP whitelisted, not delayed by milter-greylist-2.0.2

Prior to that I see a message being processed (I'm going to have to
edit pretty hard here to avoid the harvesters):

Apr 23 20:10:44 xmail sendmail[23412]: m3O0Ahk6023412:
from=<doug119@...>, size=2066, class=0, nrcpts=1,
msgid=<7ee90a250804231713j189fd043i5e0f3b55e90add73@...>,
proto=ESMTP, relay=root@localhost

In Scalix's documentation, they say incoming messages are handled this
way:  

The SMTP Relay receives a message. If the message is destined for the
Internet Mail Gateway, it is relayed to unix.in. (If the Internet Mail
Gateway is not running for any reason, the message is passed to
Sendmail.) If it is destined for the local Scalix system, it is
relayed to xport.in. Otherwise it is passed to Sendmail.

Any thoughts??  Would appreciate any insights!  I was going to try
greylisting 127.0.0.1, and whitelisting anything FROM my domain.
