It seems you've got pretty much the same setup as me; in my
/etc/exim/exim.conf I have:
qualify_domain = nestie.pigeonloft
local_domains = localhost:nestie.pigeonloft
local_domains_include_host = true
local_domains_include_host_literals = true
# This rewriting rule is particularly useful for dialup users who
# don't have their own domain, but could be useful for anyone.
# It looks up the real address of all local users in a file
and in /etc/email-addresses:
# This is /etc/email-addresses. It is part of the exim package
# This file contains email addresses to use for outgoing mail. Any local
# part not in here will be qualified by the system domain as normal.
# It should contain lines of the form:
There's no need to get rid of exim - it works fine!
