    I just installed Postfix and Courier. Postfix can receive messages (I can monitor from Webmin GUI) but when I try login inside or outside the network, it asks username and password then -ERR login failed. I try logging in with real accounts. What can be wrong. SMTP working okay but POP3 wont let me in..

    I tried "telnet localhost pop3" or "telnet 110" and both giving the same error.

    Thanks for helping

    How did you install Courier?

    after a hard try, installing/removing courier 100 times, I installed popa3d and all was solved all of a sudden.. Why it is not told in forums and websites instead of writing millions of pages about courier..

    Having the same issue with courier pop3

    Hi! I have the same issue with loging to pop3 on courier (have ispconfig installed, postfix and courier). I can see in webmin that mail is arriving in the Maildir in the specified account, but neather /mailuser, nor /webmail can log in. In both cases the same error:
    Apr 17 19:17:11 SERVER courierpop3login: Connection, ip=[::ffff:X.Y.Z.D]
    Apr 17 19:17:11 SERVER courierpop3login: LOGIN FAILED, [email protected], ip=[::ffff:X.Y.Z.D]
    Apr 17 19:17:16 SERVER courierpop3login: Disconnected, ip=[::ffff:X.Y.Z.D],

    Can you help me?
    Have tried loging in with e-mail and username as username, but nothing done. :confused:

    [email protected] is the wrong username. It must be something like web1_user. If it still doesn't work, please post the error messages again.

    I was researching through couriers files and found that in authmysqlrc (located in /etc/courier/), the file is left intend from my last configuration(other then ispconfig), and think that this is what is wrong about loging error(i have tried also with web1_USER, but no effect):
    MYSQL_SERVER localhost
    MYSQL_USERNAME mail_admin
    MYSQL_PASSWORD mail_pass
    MYSQL_PORT 3306
    MYSQL_HOME_FIELD "/home/vmail"

    This file tells courier to use other database (virtualmin created, before I removed it, but courier conf. unfortunately left untouched after ispconfig installation)
    Can you help me, what should be the content of this file for ispconfig?

    Thanks a lot!

    What's in /etc/courier/authdaemonrc?

    Here it is:

    ##VERSION: $Id:,v 1.13 2005/10/05 00:07:32 mrsam Exp $
    # Copyright 2000-2005 Double Precision, Inc. See COPYING for

    # authdaemonrc created from authdaemonrc.dist by sysconftool
    # Do not alter lines that begin with ##, they are used when upgrading
    # this configuration.
    # This file configures authdaemond, the resident authentication daemon.
    # Comments in this file are ignored. Although this file is intended to
    # be sourced as a shell script, authdaemond parses it manually, so
    # the acceptable syntax is a bit limited. Multiline variable contents,
    # with the \ continuation character, are not allowed. Everything must
    # fit on one line. Do not use any additional whitespace for indentation,
    # or anything else.

    ##NAME: authmodulelist:2
    # The authentication modules that are linked into authdaemond. The
    # default list is installed. You may selectively disable modules simply
    # by removing them from the following list. The available modules you
    # can use are: authuserdb authpam authpgsql authldap authmysql authcustom authpipe


    ##NAME: authmodulelistorig:3
    # This setting is used by Courier's webadmin module, and should be left
    # alone

    authmodulelistorig="authuserdb authpam authpgsql authldap authmysql authcustom authpipe"

    ##NAME: daemons:0
    # The number of daemon processes that are started. authdaemon is typically
    # installed where authentication modules are relatively expensive: such
    # as authldap, or authmysql, so it's better to have a number of them running.
    # PLEASE NOTE: Some platforms may experience a problem if there's more than
    # one daemon. Specifically, SystemV derived platforms that use TLI with
    # socket emulation. I'm suspicious of TLI's ability to handle multiple
    # processes accepting connections on the same filesystem domain socket.
    # You may need to increase daemons if as your system load increases. Symptoms
    # include sporadic authentication failures. If you start getting
    # authentication failures, increase daemons. However, the default of 5
    # SHOULD be sufficient. Bumping up daemon count is only a short-term
    # solution. The permanent solution is to add more resources: RAM, faster
    # disks, faster CPUs...


    ##NAME: authdaemonvar:2
    # authdaemonvar is here, but is not used directly by authdaemond. It's
    # used by various configuration and build scripts, so don't touch it!


    # Dump additional diagnostics to syslog
    # DEBUG_LOGIN=0 - turn off debugging
    # DEBUG_LOGIN=1 - turn on debugging
    # DEBUG_LOGIN=2 - turn on debugging + log passwords too
    # ** YES ** - DEBUG_LOGIN=2 places passwords into syslog.
    # Note that most information is sent to syslog at level 'debug', so
    # you may need to modify your /etc/syslog.conf to be able to see it.


    # A comma-separated list of option=value pairs. Each option is applied
    # to an account if the account does not have its own specific value for
    # that option. So for example, you can set
    # DEFAULTOPTIONS="disablewebmail=1,disableimap=1"
    # and then enable webmail and/or imap on individual accounts by setting
    # disablewebmail=0 and/or disableimap=0 on the account.


    # courierlogger(1) options, e.g. to set syslog facility


    # Options documented in ldap.conf(5) can be set here, prefixed with 'LDAP'.
