openbsd postfix pine problem

[werwer]

hello, i have installed postfix on openbsd, running great.
i installed pine but when i run it it says:

 [Folder vulnerable - directory /var/mail must have 1777 protection]

But it's working. If i chmod 1777 /var/mail it will be a security risk.
I can see on a public shell server running openbsd the file is chmoded 0755 but i don't get the error.
??

the point is that you click the links and read the content.

This is an FAQ, but it's hidden in the UW IMAP toolkit FAQ:
http://www.washington.edu/imap/IMAP-...ndex.html#7.10

> I assume it is related to locking. How do I change the permissions?

As root, do:
chmod 1777 /var/mail

Or, alternatively, install the provided mlock program as the FAQ
discusses.

Whomever told you that you can ignore it does not know what he is talking
about.

That message is annoying and persistant for a reason. It means what it
says: your INBOX folder is vulnerable to being trashed. All that needs to
happen is for a message to be delivered to your INBOX at the same time
that Pine is updating it.

This is because Pine is unable to create the .lock file necessary to
prevent this corruption, because /var/mail is protected 775. Pine does
not run with privileges, so it can not override this protection.

Become root, then "chmod 1777 /var/mail".

Alternatively, install the mlock program on /etc/mlock setgid mail.

... etc, etc ...

Another obvious solution is to pick a mail client other than pine.
