I'm pretty sure, in the US, given the ECPA, that there is no
legal prohibition to scanning _your_ mail. What may be at
issue is the legal definition of "your". I believe, for example,
that a company _may_ scan all e-mail in both direction which
uses company provided resources. This would especially be true if the
company had advised its employees that it might do so -- I believe
the term is "reasonable expectation of privacy". Companies _may_
establish a policy that all email is private. If they do that and
then scan an employees email anyway, then they have violated that
employee's reasonable expectation of privacy.
