Problem with Fedora1 and ipop3d

[Tim Alberts]

I've learned that if I set the /var/spool/mail folder permission to 777, I no 
longer get the following error.

Mailbox Vulnerable - Directory /var/spool/mail must have 1777 protection

It seems odd that something requires worldwriteable access to the 
/var/spool/mail folder.


However, the main problem persists that if I use kmail to retrieve email from 
the pop3 server, the /var/spool/mail/user email file gets written with the 
message:

>From MAILER-DAEMON Thu Apr 22 11:50:17 2004

This text is part of the internal format of your mail folder, and is not
a real message.  It is created automatically by the mail system software.
If deleted, important folder data will be lost, and it will be re-created
with the data reset to initial values.

A few people have hinted that imapd writes this to a mail file to keep track 
of which emails have been read.  How can this be happening if I have the 
imapd disabled?
