procmail locking problem

[Kenneth Stephen <y2kmvs@ebiz.austin.ibm.com>]

Hi,

	I am using Postfix on Woody as the MTA and procmail as the MDA. In
my procmail log file, I see messages such as :

procmail: Lock failure on "/var/spool/mail/y2kmvs.lock"

	The ownership of /var/spool/mail is root.mail and the permissions
are rwxrwsr-x . If this is a permissions problem, how do I fix it, and why
did this problem arise to begin with (since these are default installs of
postfix and procmail)?

Thanks,
Kenneth
