The easiest approach is to pipe it all and pass $received protocol to the
script. If mail is sent with "sendmail", the value is "local", if it's
sent with authentication but no encryption, it yields "esmtpa", with auth
and encryption it's "esmtpsa" IIRC. Your script then can make a detailed
decision what to do with this. Or you could create relevant routers making
the decision on basis of expanded $received_protocol variable.
