The key to this virus is this line:
Received: from multicam.com (adsl-64-173-247-195.dsl.lsan03.pacbell.net
[64.173.247.195])

it is your domain, but NOT your IP. What you need to do is write a rule for
that. 

Something like: (mind the line wrap!)

header NOT_ME Received =~ /^from multicam\.com
\(.{1,20}\.{1,20}\.(?:com|net|biz)\) \[[^4]\.[^22]\.[^143]\.[^67]\)/i

WHEW! THat was off the top of my head, so it may need some work ;)
