Can't find the error printed iprocmail.log

Hi,

in my "procmail.log" I found this error:

->->->->->->->->->->->->->->->->->->->->->->->->->->->->->->

procmail: Executing " (formail -r -A"X-Loop: 
m(_dot_)fihlon(_at_)mobilcom(_dot_)de" ;
cat $HOME/.mail-paketstatusdaten) | $SENDMAIL -oi -t"

procmail: Error while writing to " (formail -r -A"X-Loop:

$SENDMAIL

procmail: Assigning "LASTFOLDER= (formail -r -A"X-Loop:

procmail: Assigning "LASTFOLDER=Eingang"

Every paragraph is one big line.
My procmailrc looks like this:

->->->->->->->->->->->->->->->->->->->->->->->->->->->->->->

:0
* Subject: Paketstatusdaten*
{
    :0 c
    ${MONTHFOLDER}/Paketstatusdaten
    :0 c
    |/home/fihlomar/bin/paketstatusdaten
    :0
    | (formail -r -A"X-Loop: m(_dot_)fihlon(_at_)mobilcom(_dot_)de" ; cat
$HOME/.mail-paketstatusdaten) | $SENDMAIL -oi -t
}

I want to grep all mails with a subject starting with
"Paketstatusdaten". That works fine. Then I want to save a copy in the
folder "Paketstatusdaten". That works, too. At least I want to send a
reply to the sender with the contents of the file
".mail-paketstatusdaten" as the body of the message.

There I get the above error in my "procmail.log", but the reply is
sent. The mail arrives in my inbox, but above the formail-action I
used ":0".

Can anybody tell my why?

Thank you and forgive my bad english,
Marcus
