Okay, I guess you are technically correct from the point of view of the
internals of the mail system, but that seems like a really bad point of view
to be approaching this from. A message such as this being sent to users
should be correct from the normal point of view of the users.
An appropriate wording would have been something like:
"You are receiving this e-mail because you have been identified as
someone who either is currently using filters on MSU's legacy e-mail
service, old.mail.msu.edu, or has used filters in the past."
Just a simple change like that would have prevented this entire discussion.
