From Elendor
Syntax: +MAIL [<address>=<subject>]
This is the help file for the +MAIL command. To see the top-level help menu
for the entire mail system, type HELP mail (with no plus sign).
The +MAIL command starts a new mail message. <address> is a space-separated
list of player names, player dbrefs, mailgroup names, and/or bulletin
board names. <subject> is a text string that is the subject line of your
message. If you change your mind later, you can edit the address with the
+ADDRESS and +CC commands and the subject with the +SUBJECT command. (See
HELP EDITING.) Once you've started your message, see HELP WRITING for how
to write the text. If you don't provide an address or subject, the +MAIL
command just tells you how many mail messages you and your other
characters have.
Example 1: +mail Fred=How to skin a cat
(Starts a message to Fred with subject line "How to skin a cat")
Example 2: +mail Joe Bill Fred=Elendor's a great mush
(Starts a message to Joe, Bill, and Fred entitled "Elendor's a great mush")
Example 3: +mail admins=Quota Request
(Starts a message to the "admins" mailgroup entitled "Quota Request")
Example 4: +mail public=Who's J.R.R.?
(Starts a posting to the "public" bulletin board entitled "Who's J.R.R.?")
