Pop3d Authentication Error

how to use courier's debugging features to pinpoint the problem. 1. Turn on debugging For courier-imap, you need to set one of the following values in /usr/local/etc/authdaemonrc: DEBUG_LOGIN=1 # turn on authentication debugging DEBUG_LOGIN=2 # turn on authentication debugging AND show passwords This setting is located at the very end

of the configuration file. After changing this setting, restart the authentication daemon by running the courier imap log file "authdaemond stop" and "authdaemond start" commands. At this point, all debugging output goes to syslog at level 'debug', which is normally not authdaemon: s_connect() failed: no such file or directory shown. You will probably need to change your /etc/syslog.conf file to be able to see these messages. If you have an existing entry which says "mail.info" (which means facility 'mail', level 'info' or higher) then you

can just change this to "mail.debug". Alternatively you can add a new entry like this: *.debug /var/log/debug Don't forget to create this file, and to send a HUP signal to syslogd to make it re-read its configuration: # touch /var/log/debug # killall -1 syslogd If you don't want to mess around with your syslog configuration, you can also start authdaemond manually, and log its output to a file: /usr/local/libexec/courier-authlib/authdaemond >filename 2>&1 2. Issue
Courier Imap Authentication
a manual login You can use the authtest command to verify authentication, or go ahead and install Courier-IMAP. For courier-imap, you will get much better information by not using a mail client and manually logging in using 'telnet'. The transcript of this telnet session may give useful information as to what is going on. If you are going to report a problem to the mailing list, you should certainly include this transcript as well as the corresponding debugging output. -- to debug POP3 -- # telnet x.x.x.x 110 user USERNAME pass PASSWORD stat quit -- to debug IMAP -- # telnet x.x.x.x 143 a login USERNAME PASSWORD a examine inbox a logout -- to debug POP3 over SSL -- # openssl s_client -connect x.x.x.x:995 (then use same commands as POP3 example) -- to debug IMAP over SSL -- # openssl s_client -connect x.x.x.x:993 (then use same commands as IMAP example) This isn't an option for sqwebmail of course - just login through the web interface and check the authentication debug log which is generated. 3. Interpret the debug output First, a brief explanation of courier's authentication system. There are a number of standalone authentication modules. An authentication module exists for every authentication method. Each authentication module is installed as a shared library. When authdaemond starts, it attempts to

Member Greetings All, [EDIT] Never mind, Still have a problem... [EDIT] DISREGARD THE FOLLOWING POST! Unless your curious…. I got to thinking that if we are https://www.howtoforge.com/community/threads/virtual-users-and-domains-with-postfix-problems.19926/ to replace the “mail_admin_password” in the mysql GRANT… command, then we would http://forum.suse.pl/index.php?topic=26861.0 have to replace the “mail_admin_password” in the various config files used to process the virtual mail and login authentication to the mail database. I originally thought that the “mail_admin_password” was a passed variable (perhaps this could be made a bit clearer in the How-To, IMHO). I am concerned that the password authentication error to access the mail database is in clear text in several files on the server. In any case, all is working now. Thanks for the FAB How-To falko! I just went through the "Virtual Users and Domains with Postfix, Courier, and MySQL (Ubuntu 7.10) How-To". It was clear, clean, and processed without any errors. However, I get the following errors from my email client. no such file Your 'Inbox' folder was not polled for its unread count. Your IMAP server has closed the connection.

Co jakiś czas (losowy - problem potrafi pojawiać się co 15 minut a czasami przez kilka dni jest spokój) w logu /var/log/mail pojawia się wpis:Kod: [Zaznacz]Apr 3 12:56:46 pollux pop3d: authentication error: Input/output error Co ciekawe gdy pojawi się ten problem to sytuacja trwa zawsze ok 3 minut (+/- kilka sekund), w tym czasie nie jest możliwe zalogowanie się do systemu z poziomu programu pocztowego. System działał stabilnie od dłuższego czasu. Takie wpisy pojawiały się bardzo okazjonalnie (raz na kilka tygodni), jednak obecnie istotnie się to nasiliło.
