i want to add a filter which sends an auto-reply if there are

That works for me thanks! I just changed the line from you to:

      ext='(doc|xls|ppt|exe)'

But if i a change {MALICIOUS...} to

| formail -r -k | msmtp -t -a account < $HOME/.mailreply

Maybe try:

    FROM=`formail -rzt -xTo:`

or:

    FROM=`formail -rz -xTo:`

(depending on which address, the trusted, i.e., the "Return-Path:", or
"From", or user supplied, i.e., the "From:" or "Reply-To:", you want
the return mail to go to,) at the top of the MS detection script,
then:

    | msmtp "${FROM}" -a account < $HOME/.mailreply

Hi, this solved the formail and msmtp problem! =) 
I read on manpage that it is possible to do two or more actions for one
recipe.

procmailrc example:

:O 
* some filtering
      {
      :O c
      ! any(_at_)address(_dot_)org
      
      :O
      foo/
      }

I listet my filter below. It is the same like procmailrc example, but
the mail sent back to the sender is not saved in my local folder
$MAIL/gmx. Procmail just skips the part with the local folder. 

Ouch, found the mistake. I used an uppercase o instead of 0! Changed the
recipe to :0, now everything is working fine!
