Exim and Mailagent?

[fpage@ntrulez.oche.de (Frederick Page)]

Hi all,

I'm getting email and news from my UUCP-provider, have setup exim, inn and  
pine, tried to run Mailagent (instead of procmail), set up my ~/.forward  
according to the mailagent-docs to the following line (including the  
quotation marks):

"| exec /usr/lib/mailagent/filter -o /home/fpage/.bak"


However, in Exim's errorlog I find (all in one line):

1999-02-13 03:15:03 10BUbm-0000Dw-00 ** | exec /usr/lib/mailagent/filter -o
/home/fpage/.bak <fpage@ntrulez.oche.de> D=userforward T=address_pipe:
"exec" command not found for address_pipe transport


The corresponding entries in my /etc/exim.conf are

# Director
userforward:
  driver = forwardfile
  no_verify
  check_ancestor
  file = .forward
  modemask = 002
  filter

# Transport
address_pipe:
  driver = pipe
  return_output


What did I do wrong this time? :-(

Kind regards

Frederick
