PMDF provides support for delivery to MultiNet MM's local mailboxes. By default, such delivery is disabled (unless the user has profiled Multinet MM as their preferred mailbox format). To enable it based merely upon the presence of certain files, described below, specify MULTINET_MM_EXCLUSIVE=0 in the PMDF option file. (In addition, the PMDF option VMS_MAIL_EXCLUSIVE, 0 by default, must not be positive.) See the PMDF System Manager's Guide for a description of these options.
When delivering local mail, PMDF checks each address to see if it
corresponds to a local user. If it does, then depending upon the
setting of the PMDF options MULTINET_MM_EXCLUSIVE and
VMS_MAIL_EXCLUSIVE, PMDF may then check to see whether that user has MM
mailbox files in his or her home directory. The names of these files
are mail.txt and $hdrs$mail.txt; the former
contains message text while the latter contains pointers to individual
message headers in mail.txt. If these files exist and if
the above mentioned PMDF options are appropriately set, then PMDF
appends the new message to the message file and updates the header
pointer file. In this case delivery via VMS MAIL is entirely
circumvented.
If any of the conditions listed are not met, PMDF delivers the message using VMS MAIL. This delivery strategy is not enabled by default; configuration changes must be made to enable it.
Delivery to MM can be disabled unconditionally by setting MULTINET_MM_EXCLUSIVE=-3 or by setting VMS_MAIL_EXCLUSIVE=3 in the PMDF option file.
Delivery to VMS MAIL can be disabled unconditionally by setting VMS_MAIL_EXCLUSIVE=-3 or by setting MULTINET_MM_EXCLUSIVE=3 in the PMDF option file.
