In case you've been wondering how the SYS$MAIL lists work because you never
knew or you just plain forgot, here is an updated description.

A mail distribution list is simply a file that contains a list of VAX usernames
to whom you want your message distributed. Each VAX contains in its directory
SYS$MAIL a select group of distribution lists that automatically get updated
each time a person is added to a system. The usernames are collected in groups
(some aribtrary, some based on job function) and two lists for each group are
created. One list, the .DIS file, contains the list of all users on all systems
in the network that fall into the group and the other list, the .UAF file,
contians the list of users only on the host system. You are free to use the
distribution lists located on any system in the network.

The following is a list of group types that have been established on all
systems in the network. The "real people" refers to regular users. Non "real
people" are those like DECNET, SYSTEM, FIELD, etc.

	Your choices for names of lists are:
COINOP		All real people who have accounts.
JUNK		All real people who don't mind junk mail.
WPUSERS		MUSE people (Publications and secretaries)
SCUSER		Sci-Cards people
ENGINEER	All COINOP people who arent WPUSERS or SCUSERs.
		   (before you ask, ENGINEER includes programmers too)
CAD		IC design people
UNIX		People who have expressed an interest in the UNIX O/S.
???????		More to come, watch this space

You have to ask to have your name included in UNIX or excluded from JUNK.

For example: if your host system is KIM and you want to send mail to JUNK,
(basically everyone in the network) then to MAIL's prompt "To:" respond:

	@SYS$MAIL:JUNK

(MAIL uses a default distribution list file type of .DIS)
If you only wanted your mail to go only to the JUNK collectors on KIM, then
type:

	@SYS$MAIL:JUNK.UAF

It gets confusing beyond this, but you could also send mail to users on a
specific system by including the node name. For example if your host system
is KIM and you want to send JUNK mail only to the user's on GRUMPY, then type:

	@GRUMPY::SYS$MAIL:JUNK.UAF

You should be aware that the JUNK.DIS (as well as all other .DIS files) in
SYS$MAIL on all systems are equivalent. That is, putting a node name on any
.DIS file only results in making the mailing take longer (the system has to
go to the remote node first to get the master list instead of looking on the
host system for the same list).

	Confused? You won't be after the next episode....

	Happy mailing, ('cept to the one called KIM::RICE)
