There is no "right permissions". What permissions you need depend entirely on what you want to do.
On a directory, 'x' permission allows people to cd into it, 'r' allows people to ls in it, and 'w' allows people to create or delete files. Read permission is 4, write permission is 2, execute permission is 1. Decide what permissions you want, add them up, and you get a number between 0 and 7 inclusive.
Do it three times. The last number applies to random passers by, the middle one applies to people in the group owning the dir, and the first applies to the actual user who owns the dir. Don't think about who you want to restrict -- think about who you need to allow, and grant nothing else.
Having done that, you have three digits, like 740. That gives full permissions to the owner, read and ls permission to the group, and nothing at all to anyone else.
For a temp folder or test folder, you'd also want to use the sticky bit, chmod u+s, on the directory itself. This changes how directory permissions work so that files can only be deleted by their owners, having simple write-permissions to the directory itself becomes no longer sufficient.

folders(1) General Commands Manual folders(1)
NAME
folders - list folders and contents (only available within the message handling system, mh)
SYNOPSIS
folders [+folder] [msg] [options]
OPTIONS
Lists only the name of folders, with no additional information. This is faster because the folders need not be read. Prints a list of the
valid options to this command. Lists the contents of the folder-stack. No +folder argument is allowed with this option. Re-numbers mes-
sages in the folders. Messages are re-numbered sequentially, and any gaps in the numbering are removed. The default operation is -nopack,
which does not change the numbering in the folder. Discards the top of the folder-stack, after setting the current folder to that value.
No +folder argument is allowed with this option. This corresponds to the popd operation in the C-shell; see csh(1). The -push and -pop
options are mutually exclusive: the last occurrence of either one overrides any previous occurrence of the other. Pushes the current
folder onto the folder-stack, and makes the +folder argument into the current folder. If +folder is not given, the current folder and the
top of the folder-stack are exchanged. This corresponds to the pushd operation in the C-shell; see csh(1). The -push switch and the -pop
switch are mutually exclusive: the last occurrence of either one overrides any previous occurrence of the other. Lists folders recur-
sively. Information on each folder is displayed, followed by information on any sub-folders which it contains. Displays only the total
number of messages and folders in your Mail directory. This option does not print any information about individual folders. It can be sup-
pressed using the -nototal option.
The defaults for folders are:
+folder defaults to all msg defaults to none -nofast -noheader -nototal -nopack -norecurse
DESCRIPTION
The folders command displays the names of your folders and the number of messages that they each contain.
The folders command displays a list of all the folders in your Mail directory. The folders are sorted alphabetically, each on its own line.
This is illustrated in the following example: Folder # of messages ( range ); cur msg (other files)
V2.3 has 3 messages ( 1- 3).
adrian has 20 messages ( 1- 20); cur= 2.
brian has 16 messages ( 1- 16).
chris has 12 messages ( 1- 12).
copylog has 242 messages ( 1- 242); cur= 225.
inbox+ has 73 messages ( 1- 127); cur= 127.
int has 4 messages ( 1- 4); cur= 2 (others).
jack has 17 messages ( 1- 17); cur= 17.
TOTAL= 387 messages in 8 folders.
The plus sign (+) after inbox indicates that it is the current folder. The information about the int folder includes the term (others).
This indicates that the folder int contains files which are not messages. These files may be either sub-folders, or files that do not
belong under the MH file naming scheme.
The folders command is identical to the effect of using the -all option to the folder command.
If you use folders with the +folder argument, it will display all the subfolders within the named folder. as shown in the following exam-
ple:
% folders +test Folder # of messages ( range ); cur msg (other files) test+ has 18 messages ( 1- 18);
(others). test/testone has 1 message ( 1- 1). test/testtwo has no messages.
TOTAL= 19 messages in 3 folders.
See refile(1) for more details of sub-folders.
RESTRICTIONS
MH does not allow you to have more than 100 folders at any level in your Mail directory.
PROFILE COMPONENTS
Path: To determine your MH directory
Folder-Protect: To set protections when creating a new folder
Folder-Stack: To determine the folder stack
lsproc: Program to list the contents of a folder
FILES
The user profile.
