The reason I give this relatively less weight is that we are only
using it to try to guess that mail was personal. Necessarily this
will always be a guess. I'm willing to accept that it will guess wrong
on those rare occasions when mail goes to users who both have the same
local part. I suppose it's possible to imagine a senario where
multiple users with the same local part interact heavily, but I
suspect this is true with lower probability than the case where users
within a single domain omit the domain in email. I suppose we need
some way to customize it in any case.
