Why implicit lockfile from "/usr/sbin/sendmail

Hello

I would like to create the following:

One user-jos recieved only mail from domain ,domain1, domain2
All the other mail has to forward to second(_at_)user(_dot_)com

Here's the procmailrc

SHELL=/bin/sh
LOGFILE=$MAILDIR/.procmail-log

:0 H:
*^From:.*(domain.com|domain2.com|domain3.com)
/var/spool/mail/user-jos

:0c:
! second(_at_)user(_dot_)com



procmail-log shows

procmail: Couldn't determine implicit lockfile from "/usr/sbin/sendmail"
> From myname(_at_)yahoo(_dot_)com  Wed Dec  3 12:23:45 2003
 Subject: test-mail
  Folder: /usr/sbin/sendmail -oi second(_at_)user(_dot_)com
