He isn't. He's using kevin@localhost. Something at your end is seeing
the '@localhost' and rewriting it to your domain name. For the same
reason, other people will be thinking he's faking their domain names.

Have a look in the challenge-response flamewar thread - Alan Connor
had a similarly broken header and people were thinking the same thing
about him.

Kevin, if you're using exim, try something like this: (I'm assuming
your local hostname is 'debian' based on a quick poke through your
posts)

From /etc/exim/exim.conf:

######################################################################
#                      REWRITE CONFIGURATION                         #
######################################################################


# There are no rewriting specifications in this default configuration file.


# 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

*@debian               ${lookup{$1}lsearch{/etc/email-addresses}\
						{$value}fail} frFs


From /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:
#
#user: someone@isp.com
#otheruser: someoneelse@anotherisp.com

kevin: kevin@pacific.net.au
