  You must mean a "new" public release.  After all his 2.2 release in 1990
(?) is what started all of this.

  4 and 5 are probably the same.  UUNet just uses an older version of the
Borderware stuff.

  Besides the newest Borderware Zmailer has a bug that I just detected.
Send borderware.com a HELP command and you will see what I mean.

  I don't know if this really exists.  The SMTP receiver looks like
Zmailer 2.2 with the versions removed (no ESMTP support just like
stock Zmailer-2.2).  They strangely removed Rayan's trademark from the
help, but left the zmhacks@cs.toronto.edu as a contact for server
