A user sent an email to 5 aliases. One of the alias file had an invalid

550 /alias_group: line 10: gone_user... User unknown
procmail: Lock failure on "/var/spool/mail/user1.lock"
procmail: Lock failure on "/var/spool/mail/user2.lock"
.
.
The line starting with "550" is from the invalid address. When sendmail
sends a bounce message, it includes any output generated by *all* the
deliveries for that message. The procmail messages were generated by
procmail while delivering to 'user1', 'user2', etc, but it (procmail)
still considered the delivery successful.
At this point you should probably try to figure out why procmail can't
create lockfiles in /var/spool/mail. Is /var/spool/mail NFS mounted?
What are the permissions on it? If you have an /etc/procmailrc file,
what does it contain? What version of procmail are you using?
