Baffled - "unknown virtual host" when creating new list

Question

*I am getting this message:*
_Error: Unknown virtual host: mail.riverstoneschool.org_
*when I attempt to create a new list. What's baffling is that we don't have any virtual domains and the domain listed in the message is our primary domain. Here's the mm_config.py: (minus the initial comments)*
from Defaults import *
# Put YOUR site-specific settings below this line.
MTA = 'Postfix'
DEFAULTEMAILHOST = 'mail.riverstoneschool.org'
DEFAULTURLHOST = 'mail.riverstoneschool.org'
DEFAULTURLPATTERN = 'https://%s/mailman/'
IMAGE_LOGOS = '/images/'
DEFAULTADMIN_MEMBERCHUNKSIZE = 150
OWNERSCAN_DELETE_THEIR_OWNLISTS = yes
*In case it's relevant, here's the dig results for "mail.riverstoneschool.org" when run from the server in question (ie: from mail.~ itself). Also in case it's relevant, this Mac server is the one hosting DNS, too:*
rs-server-ws:Mailman matthewmiller$ dig mail.riverstoneschool.org
; <<>> DiG 9.4.3-P3 <<>> mail.riverstoneschool.org

Thanks in advance for any assistance you can offer!

Hi Kevin,
I think you have to set the query specification for the data provider you created. If you don't, no object is available (that'w why you received a such error).
Best regards,
