Dunno if it helps but, coincidentally enough, I've transitioned this
list to using a feature of the mailing list software which adds a
"X-IsSubscribed: yes" to the header of a message if the sender was
subscribed.

This isn't foolproof since it just does a raw lookup of the senders
email address in the subscriber database and could be fooled by extra
"stuff" in an email address but if do you see the field, you can be
sure that the person who sent the message is subscribed.
