[Mailman-Users] no mail... looks like an exim config problem

[Kirk R. Wythers]

I need to configure exim for a virtual domain. The uname of my machine
in lorax.forestry.umn.edu, the virtual domain that I want to run mailman
to/from is neighborsunited.net. 

Here is the exim log error:
2003-08-06 12:14:53 remote host address is the local host:
neighborsunited.net (while verifying
<testlist-bounces at neighborsunited.net> from
host localhost.forestry.umn.edu (lorax.forestry.umn.edu) [::1])

If I add the domain neighborsunited.net as the primary hostname, will
that take care of it? 

# primary_hostname = 
primary_hostname = neighborsunited.net

or do I also need something here? 

domainlist local_domains = @
domainlist relay_to_domains =
hostlist   relay_from_hosts = localhost

Lastly, how does one HUP exim?

Thanks
