Here is the archive of the thread:

http://www.exim.org/pipermail/exim-users/Week-of-Mon-20030203/049332.html

Basically all that is needed is a note in the port explaining that some 
other ports, such as Mailman, will attempt to communicate using IPv6 and 
be denied using the default configure file.  I solved the problem by 
adding:

local_interfaces = 0.0.0.0

to my exim configure file, which tells exim to listen on all IPv4 
ports.  Another solution is to add:

hostlist   relay_from_hosts = 127.0.0.1 : ::::1

which tells exim to allow relaying from both IPv4 and IPv6 localhost.
