What is "para-mail"

Para Mail was a proprietary, electronic mail client that was developed and maintained by Kris Land and his team. It was originally released in 1985 for MS-DOS, but was subsequently ported to Microsoft Windows. A version for Apple Macintosh also used to be available.

On January 3, 1990, it was announced that Paradox Development of Para-Mail was acquired by Office Automation Systems later known as OCTuS, Inc.
