.forward problem

Hi all,

did anyone see allready the following message?

/usr/people/palme/.forward: line 1: |"/usr/local/bin/procmail # Palme"... User 
palme(_at_)wrin27(_dot_)urz(_dot_)uni-wuppertal(_dot_)de doesn't have a valid 
shell for mailing to programs
/usr/people/palme/.forward: line 1: |"/usr/local/bin/procmail # Palme"... User 
palme(_at_)wrin27(_dot_)urz(_dot_)uni-wuppertal(_dot_)de doesn't have a valid 
shell for mailing to programs
/usr/people/palme/dead.letter... Saved message in /usr/people/palme/dead.letter

May be, it comes from sendmail -- but what does it mean and how can I
ship around?

Thanks in advance,
