Having made all necessary changes, the mailer supplied with DECUS UUCP
should be deinstalled; users will be confused as to which to use
otherwise. In any case, incoming mail will use PMDF, not the UUCP
mailer. To deinstall the UUCP mailer, edit
UUCP_BIN:uucp_systartup.com to remove all references to
MAIL$PROTOCOL_* logicals, remove the line to reinstall
mail.exe with privileges (this is not needed by the PMDF
interface to VMS MAIL) and remove the line that installs the image
UUCP_BIN:uucp_mailshr.
