> Are all "Undisclosed recipient" type emails spam?
No. Unfortunately there is a low correlation there. In particular the Sendmail vacation(1) program autoresponds with out of the office messages without bothering to add a To: header and generates these types of messages as a normal course of action. They occur other places with a regularity as well.
