I don't know that the Crosswell (Columbia) mailer has ever been in the
public domain.  I believe it is copyrighted by Columbia, but is available
free of charge to BITNET users or some such thing.  Anyway, it has long
since been superseded by the VM Mailer Version 2, which is copyrighted
(I think) by both Columbia and Princeton under the same sort of deal.  I
don't know if there is any way to get it on tape.

There is a mailer for MVS/TSO, by the way, known as UCLA Mail, but you
probably already know about that.  It isn't free, but it's probably a
bargain.
