PMDF System Manager's Guide

The mail server is a PMDF channel program associated with the mailserv channel. The mail server runs as a master channel program; there is no slave program associated with the channel.

The mail server only processes mail. It does not process interactive messages as the LISTSERV servers on BITNET do. It is limited to processing mail messages, interpreting the body of the message as commands. The mail server does not allow access to files outside of the directory tree pointed at by the PMDF_MAILSERV_FILES_DIR logical (on OpenVMS systems) or PMDF tailor file option (on UNIX systems) or Registry entry (on NT systems).
