This is an ELM mail agent clone called PTMail. It runs on VMS.

It offers many features above normal VMS Mail.

 This program replaces (at least to some degree) VAX/VMS MAIL. It is supposed
 to look and feel somewhat like Elm, however a few things are different. I 
 think one of the confusing differences is the fact that you exit PTmail with 
 'x' and not with 'q'uit at least when you want to save your changes. Elm is 
 exactly the otherway around for who knows what reason.
 The previous version of PTmail was simply a 'wrap-around' for the MAIL program
 itself. Very clumsy but it worked to some degree. This version, is a complete
 rewrite of all MAIL routines and VAX/VMS MAIL is no longer used as a 
 foundation.
