Problem mit Debian Jessie / Postfix / Dovecot

[Ammes]

Hallo,

 

ich habe oben beschrieben Konfiguration eingerichtet. Die Konfigurationsdateien habe ich jetzt viermal überprüft bzw. neu eingegeben. 

 

Der Server kann auf angelegten Mail-Adressen Mails von aussen empfangen.

 

Ich kann aber keine Mails per IMAP abrufen.

 

Folgende Fehlermeldung erscheint in den Logs

 

Feb 26 10:42:49 Server-Name dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=Home-IP, lip=Server-IP, session=<vqZHH6ksdABdugT3>

 

Irgendjemand eine Idee, wo ich noch suchen kann.

 

 

Herzlichen Dank

Ammes

Das hat leider nicht geholfen :-((

 

Sonst noch jemand eine Idee? 

 

Viele Grüße

Poste bitte mal deine /etc/dovecot/conf.d/10-auth.conf

Hallo,,

 

##

## Authentication processes

##

 

# Disable LOGIN command and all other plaintext authentications unless

# SSL/TLS is used (LOGINDISABLED capability). Note that if the remote IP

# matches the local IP (ie. you're connecting from the same computer), the

# connection is considered secure and plaintext authentication is allowed.

# See also ssl=required setting.

disable_plaintext_auth = no

 

# Authentication cache size (e.g. 10M). 0 means it's disabled. Note that

# bsdauth, PAM and vpopmail require cache_key to be set for caching to be used.

#auth_cache_size = 0

# Time to live for cached data. After TTL expires the cached record is no

# longer used, *except* if the main database lookup returns internal failure.

# We also try to handle password changes automatically: If user's previous

# authentication was successful, but this one wasn't, the cache isn't used.

# For now this works only with plaintext authentication.

#auth_cache_ttl = 1 hour

# TTL for negative hits (user not found, password mismatch).

# 0 disables caching them completely.

#auth_cache_negative_ttl = 1 hour

 

# Space separated list of realms for SASL authentication mechanisms that need

# them. You can leave it empty if you don't want to support multiple realms.

# Many clients simply use the first one listed here, so keep the default realm

# first.

#auth_realms =

 

# Default realm/domain to use if none was specified. This is used for both

# SASL realms and appending @domain to username in plaintext logins.

#auth_default_realm = 

 

# List of allowed characters in username. If the user-given username contains

# a character not listed in here, the login automatically fails. This is just

# an extra check to make sure user can't exploit any potential quote escaping

# vulnerabilities with SQL/LDAP databases. If you want to allow all characters,

# set this value to empty.

#auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@

 

# Username character translations before it's looked up from databases. The

# value contains series of from -> to characters. For example "#@/@" means

# that '#' and '/' characters are translated to '@'.

#auth_username_translation =

 

# Username formatting before it's looked up from databases. You can use

# the standard variables here, eg. %Lu would lowercase the username, %n would

# drop away the domain if it was given, or "%n-AT-%d" would change the '@' into

# "-AT-". This translation is done after auth_username_translation changes.

#auth_username_format = %Lu

 

# If you want to allow master users to log in by specifying the master

# username within the normal username string (ie. not using SASL mechanism's

# support for it), you can specify the separator character here. The format

# is then <username><separator><master username>. UW-IMAP uses "*" as the

# separator, so that could be a good choice.

#auth_master_user_separator =

 

# Username to use for users logging in with ANONYMOUS SASL mechanism

#auth_anonymous_username = anonymous

 

# Maximum number of dovecot-auth worker processes. They're used to execute

# blocking passdb and userdb queries (eg. MySQL and PAM). They're

# automatically created and destroyed as needed.

#auth_worker_max_count = 30

 

# Host name to use in GSSAPI principal names. The default is to use the

# name returned by gethostname(). Use "$ALL" (with quotes) to allow all keytab

# entries.

#auth_gssapi_hostname =

 

# Kerberos keytab to use for the GSSAPI mechanism. Will use the system

# default (usually /etc/krb5.keytab) if not specified. You may need to change

# the auth service to run as root to be able to read this file.

#auth_krb5_keytab = 

 

# Do NTLM and GSS-SPNEGO authentication using Samba's winbind daemon and

# ntlm_auth helper. <doc/wiki/Authentication/Mechanisms/Winbind.txt>

#auth_use_winbind = no

 

# Path for Samba's ntlm_auth helper binary.

#auth_winbind_helper_path = /usr/bin/ntlm_auth

 

# Time to delay before replying to failed authentications.

#auth_failure_delay = 2 secs

 

# Require a valid SSL client certificate or the authentication fails.

#auth_ssl_require_client_cert = no

 

# Take the username from client's SSL certificate, using 

# X509_NAME_get_text_by_NID() which returns the subject's DN's

# CommonName. 

#auth_ssl_username_from_cert = no

 

# Space separated list of wanted authentication mechanisms:

#   plain login digest-md5 cram-md5 ntlm rpa apop anonymous gssapi otp skey

#   gss-spnego

# NOTE: See also disable_plaintext_auth setting.

auth_mechanisms = plain login

 

##

## Password and user databases

##

 

#

# Password database is used to verify user's password (and nothing more).

# You can have multiple passdbs and userdbs. This is useful if you want to

# allow both system users (/etc/passwd) and virtual users to login without

# duplicating the system users into virtual database.

#

# <doc/wiki/PasswordDatabase.txt>

#

# User database specifies where mails are located and what user/group IDs

# own them. For single-UID configuration use "static" userdb.

#

# <doc/wiki/UserDatabase.txt>

 

#!include auth-deny.conf.ext

#!include auth-master.conf.ext

 

#!include auth-system.conf.ext

!include auth-sql.conf.ext

#!include auth-ldap.conf.ext

#!include auth-passwdfile.conf.ext

#!include auth-checkpassword.conf.ext

#!include auth-vpopmail.conf.ext

#!include auth-static.conf.ext

 

 

Sollte eigentlich genau so sein, wie in der Anleitung vorgegeben.

Postfix + Dovecot anschließend Neu gestartet?

[Ammes]

Ich traue mich gar nicht es zu sagen.

 

Dovecot habe ich jeweils immer neu gestartet (wie in der Anleitung), Postfix hatte ich nur neu gestartet nach den SMTP Änderungen, an der Stelle hier nicht mehr.

 

Lange Rede kurzer Sinn, es geht jetzt.

 

Mann, bin ich blöd

 

 

Vielen herzlichen Dank für die Hilfe.

Macht doch nichts, solange es jetzt funktioniert passt doch alles

Noch eine Frage:

 

Gibt es irgendwo eine gute Anleitung um TLS unter dovecot zu aktivieren /installieren?

Du müsstest Plaintext altivieren, insofern kein TLS verwendet wird. Steht soweit ich weiß in der 10-auth.conf.

 

#disable_plaintext_auth = yes

zu:

disable_plaintext_auth = no
