POP3 geht ohne SSL nicht: Unknown AUTHORIZATION state command - Exim4 und ipop3d

[Martin Jürgens <martin@gamesplace.info>]

Hallo,
und wieder hab' ich eine Frage:

Wenn ich E-Mails von meinem Server (mit Confixx) versuche abzurufen, 
kommt die Meldung Unknown AUTHORIZATION state command. Wenn ich SSL in 
meinem E-Mail Client aktiviere, funktioniert alles einwandfrei. Ich 
würde gerne POP3 auch ohne SSL verwenden, nur finde ich keine 
Möglichkeit. Hier mal die /etc/exim4/conf.d/auth/30_exim4-config_examples:


### auth/30_exim4-config_examples
#################################

# The examples below are for server side authentication; they allow two
# styles of plain-text authentication against an CONFDIR/passwd file
# which should have user IDs in the first column and crypted passwords
# in the second. The columns need to be separated by ':'. For CRAM-MD5
# exim needs access to the UNECRYPTED passwd - the example below assumes
# it is avalable in the third column of CONFDIR/passwd

plain_server:
  driver = plaintext
  public_name = PLAIN
  server_condition = "${if 
crypteq{$3}{${extract{1}{:}{${lookup{$2}lsearch{CONFDIR/passwd}{$value}{*:*}}}}}{1}{0}}"
  server_set_id = $2
  server_prompts = :

login_server:
  driver = plaintext
  public_name = LOGIN
  server_prompts = "Username:: : Password::"
  server_condition = "${if 
crypteq{$2}{${extract{1}{:}{${lookup{$1}lsearch{CONFDIR/passwd}{$value}{*:*}}}}}{1}{0}}"
  server_set_id = $1

cram_md5_server:
  driver = cram_md5
  public_name = CRAM-MD5
  server_secret = 
${extract{2}{:}{${lookup{$1}lsearch{CONFDIR/passwd}{$value}fail}}}
  server_set_id = $1

# Here is an example of CRAM-MD5 authentication against PostgreSQL:
#
# psqldb_auth:
#   driver = cram_md5
#   public_name = CRAM-MD5
#   server_secret = ${lookup pgsql{SELECT pw FROM users WHERE username = 
'${quote_pgsql:$1}'}{$value}fail}
#   server_set_id = $1

# Authenticate against local passwords using sasl2-bin
#
# plain_saslauthd:
#   driver = plaintext
#   public_name = PLAIN
  # don't send system passwords over unencrypted connections
#   server_advertise_condition = ${if eq{$tls_cipher}{}{0}{1}}
#   server_condition = ${if saslauthd{{$2}{$3}}{1}{0}}
#   server_set_id = $2
#   server_prompts = :

# See /usr/share/doc/exim4-base/README.SMTP-AUTH

# These examples below are the equivalent for client side authentication.
# They get the passwords from CONFDIR/passwd.client. This file should have
# three columns separated by colons, the first contains the name of the
# mailserver to authenticate against, the second the username and the third
# contains the password.

### # example for CONFDIR/passwd.client
### mail.server:blah:secret
### # default entry:
### *:bar:foo

#plain:
#  driver = plaintext
#  public_name = PLAIN
#  server_condition = "${if pam{$2:$3}{1}{0}}"
#  server_set_id = $2
#login:
#  driver = plaintext
#  public_name = LOGIN
#  server_prompts = "Username:: : Password::"
#  server_condition = "${if pam{$1:$2}{1}{0}}"
#  server_set_id = $1


Ich benutze ein aktuelles Debian Testing. Solltet ihr weitere Inhalte 
von Config Dateien benötigen, um das Problem einzugrenzen, so sagt mir 
einfach den Pfad!

Für Hilfe wäre ich sehr dankbar.
