OK, this message was received by courier-mta from "gpg". So the question
is, where does gpg have gotten the local part?

    Michelle

Note:  The "M" is a BIG letter!

So I have written a fake sendmail to see, what it get and gotten

This mean, gpg was looking into the GECOS field and gotten it wrong. gpg
should ONLY use the LOGIN and NOT the GECOS field and in this case,  the
MTA will do the right thing since my login is "michelle.konzack"

michelle.konzack:x:1000:1000:Michelle Konzack,1,0033388452356,,michelle.konzack at freenet.de:/home/michelle.konzack:/bin/bash

OK, gpg has used a WRONG "From:" and then courier  has  used  the  first
valid string it has found

   Michelle

and droped the rest.  Since "Michelle" dos not exist on my  system,  the
Mail will fail in any case

Also I should note, that I am on a VHost  and  for  this,  no  MTA  will
rewrite  anything.  Because  it  can't.  I  want  to  write  my  E-Mails
wherever I am in my Network and my LOGIN  is  always  "michelle.konzack"
and do not tell me, I have to setup the MTA's of 2800 Servers and VHosts
to rewrite any possibilities in a GECOS field can apear...

exim, postfix and courier can not do it!

HOW o you think, should  exim/postfix/courier  rewrite  a  wrongly  used
"localpart"?

NO, the business for "gpg" is, to use ONLY the LOGIN name and not  using
the GECOS field

My new FileServer (installed for 11 days) is Etch with

gnupg:
  Installiert:1.4.6-2
  Mögliche Pakete:1.4.6-2
  Versions-Tabelle:
 *** 1.4.6-2 0
        500 file: etch/main Packages
        100 /var/lib/dpkg/status
courier-mta:
  Installiert:0.53.3-5
  Mögliche Pakete:0.53.3-5
  Versions-Tabelle:
 *** 0.53.3-5 0
        500 file: etch/main Packages
        100 /var/lib/dpkg/status

and the error persists...

QUESTION:  Why does gpg not respect the environement variable SENDMAIL
           which is set to "/usr/sbin/sendmail_offline_wraper"?
