Dave Funk gave you a better suggestion: whitelist authenticated
vodaphone emails and create some aggressive rules to catch the fakes.
More to the point; create aggressive rules to catch -any- message that
claims to be a vodafone bill (real or fake) and whitelist_auth
vodaphone emails.
This way you don't have to try to figure out exactly how to identify
the fakes, you just push all "vodafone bill messages" off the cliff
and count on the whitelist_auth rule to be a safety net that will
rescue the real ones.
