Starnge postmaster email about .forward entry

Hey all!
I got this resulting from a failed delivery from postmaster at this AIX
machine.

Subject: Postmaster warning: /users/cjraven/.forward: line 1: "|IFS=' ' &&
exec /usr/local/bin/procmail -f- || exit 75 ... Unbalanced '"' 

Any ideas anyone?
Regards & TIA
