new name issue

[Matt Price <matt.price@utoronto.ca>]

I've encountered another difficulty with Mailman.  Using the web
interface to add new lists (at
http://any-valid-host-name-for-my-computer/cgi-bin/mailman/create) I
am unable to actually generate the new list.  I get the following
error at the top of the page generated by Mailman: 

Error: Unknown virtual host: any-valid-host-name-for-my-computer 

This is wierd since I've been able to add lists from the command line
without any difficulty.  Anyone seen this before?

Thanks,
matt
