Some of you may have noticed the presence of files in your home directory
with the name MAIL$nnnnnnnnnnnnnnnn.MAI where the "n" is a arbitrary number.
These files are created when your mail message is greater than 3 disk blocks
(1500 bytes) in length. There's one file for each of your long messages. You can
make MAIL put these files in a different directory if you want by issuing the
command:

	MAIL> SET MAIL_DIRECTORY [.sub_directory_name]

where the [.sub_directory_name] is one of your choosing. For example:

	MAIL> SET MAIL_DIRECTORY [.MAIL]

will put "folder" files in the subdirectory [.MAIL] and out of your way.
