Presumably the definitions of DEFAULT_EMAIL_HOST and DEFAULT_URL_HOST
in  Defaults.py are wrong since you didn't configure them and your
host is 'Unknown'. Therefore, there are two problems with the above.

The first problem is you want to remove the erroneous VIRTUAL_HOSTS
entry created in Defaults.py. This is not critical, but it is good

The main problem is you need to move the


directive to a point AFTER you have redefined DEFAULT_EMAIL_HOST and
DEFAULT_URL_HOST. Otherwise, you are just re-adding the erroneous
entry from Defaults.py.

So what you want is

DEFAULT_EMAIL_HOST = 'mailinglists.state.or.us'
DEFAULT_URL_HOST = 'mailinglists.state.or.us'

(the first 3 can be in any order, but the add_virtualhost() must be the
last of the 4.

You may need to run fix_url on the lists you created from the command
line. See the above referenced FAQ 4.62 and also 4.69.
