Description of problem:
When I retrieve mail using the POP3 server in fedora-1's new imap 
package, I get "Mailbox vulnerable" messages in /var/log/maillog:

Nov  8 23:11:54 host ipop3d[1172]: pop3 service init from 12.34.56.78
Nov  8 23:11:54 host ipop3d[1172]: Mailbox vulnerable - 
directory /var/spool/mail must have 1777 protection
Nov  8 23:11:54 host ipop3d[1172]: Login user=username host=
[12.34.56.78] nmsgs=0/0
Nov  8 23:11:54 host ipop3d[1172]: Mailbox vulnerable - 
directory /var/spool/mail must have 1777 protection
Nov  8 23:11:54 host ipop3d[1172]: Logout user=username host=
[12.34.56.78] nmsgs=0 ndele=0

Problem did not exist in Red Hat Linux 9.


Version-Release number of selected component (if applicable):
imap-2000d-3

How reproducible:
Always

Steps to Reproduce:
1. Install imap-2000d-3
2. Enable POP3 service by editing /etc/xinetd.d/ipop3, 
removing "disable=yes", and reloading xinetd
3. Send mail to a user on the system
4. Retrieve that mail using POP3
5. Check /var/log/maillog
  
Additional info:

My guess is that the directory doesn't really need 1777 permissions; 
imap may just be built with the wrong options. An old Red Hat Linux 
release from several years ago (6.0 maybe; I'm not sure) gave this 
same error, and it got fixed without changing the permissions on the 
directory.
