In the following examples I discussed that rather often private use of
e-mail is permitted and that you are likely to need a written statement
of every employee to be allowed to do something about spam. The reason:
a false-positive of your anti-spam-solution might affect their private
e-mail. "Doing something about spam" includes rejecting at smtp-time.
Anti-virus is different. A virus might bring down the company. If you
have bad luck with a virus, you are out of business. The number of
false-posivites in virus-detection is considered to be low. Therefore
you are allowed to detect and reject at smtp-time.
