Fehler beim Einrichten von SASL / SMTP-AUTH

Post by oj69 »

Hallo zusammen,

nach stundenlangem googeln und verschiedene Varianten erfolglos testen, brauche ich die Hilfe von einem Postfix-Experten hier. Eigentlich bin ich ganz fit im Linux aber in der Konstellation Postfix - SASL habe ich gerade einen Hänger :-o.

Ich bekomme immer einen Fehler "xsasl_cyrus_server_get_mechanism_list: no applicable SASL mechanisms", wenn emails vom postfix empfangen werden sollen. Das passiert, wenn ich in der main.cf "smtpd_sasl_auth_enable = yes" setze. Mein Server läuft sonst ohne Probleme. Allerdings will ich nun auch für Thunderbird-Clients aus dem Internet den Mailversand ermöglichen.

Mein Umfeld:
Ubuntu 12.04.4 LTS Server auf einem V-Server
Zarafa Community Edition (aktuelle Version)
Postfix, Amavis usw.

main.cf

Code: Select all

#
# Settings for saslauthd daemon
# Please read /usr/share/doc/sasl2-bin/README.Debian for details.
#

# Should saslauthd run automatically on startup? (default: no)
START=yes

# Description of this saslauthd instance. Recommended.
# (suggestion: SASL Authentication Daemon)
DESC="SASL Authentication Daemon"

# Short name of this saslauthd instance. Strongly recommended.
# (suggestion: saslauthd)
NAME="saslauthd"

# Which authentication mechanisms should saslauthd use? (default: pam)
#
# Available options in this Debian package:
# getpwent  -- use the getpwent() library function
# kerberos5 -- use Kerberos 5
# pam       -- use PAM
# rimap     -- use a remote IMAP server
# shadow    -- use the local shadow password file
# sasldb    -- use the local sasldb database file
# ldap      -- use LDAP (configuration is in /etc/saslauthd.conf)
#
# Only one option may be used at a time. See the saslauthd man page
# for more information.
#
# Example: MECHANISMS="pam"
#MECHANISMS="pam"
MECHANISMS="rimap"

# Additional options for this mechanism. (default: none)
# See the saslauthd man page for information about mech-specific options.

# Other options (default: -c -m /var/run/saslauthd)
# Note: You MUST specify the -m option or saslauthd won't run!
#
# WARNING: DO NOT SPECIFY THE -d OPTION.
# The -d option will cause saslauthd to run in the foreground instead of as
# a daemon. This will PREVENT YOUR SYSTEM FROM BOOTING PROPERLY. If you wish
# to run saslauthd in debug mode, please run it by hand to be safe.
#
# See /usr/share/doc/sasl2-bin/README.Debian for Debian-specific information.
# See the saslauthd man page and the output of 'saslauthd -h' for general
# information about these options.
#
# Example for chroot Postfix users: "-c -m /var/spool/postfix/var/run/saslauthd"
# Example for non-chroot Postfix users: "-c -m /var/run/saslauthd"
#
# To know if your Postfix is running chroot, check /etc/postfix/master.cf.
# If it has the line "smtp inet n - y - - smtpd" or "smtp inet n - - - - smtpd"
# then your Postfix is running in a chroot.
# If it has the line "smtp inet n - n - - smtpd" then your Postfix is NOT
# running in a chroot.
