    Hello everyone.. I just got done following Virtual Users And Domains With Postfix, Courier And MySQL (CentOS 5.1)

    everything seems to be working but i can't login to download emails with Thunderbird.

    when I look in the log files i get the following error message:
    Feb 18 12:05:15 maleshafske pop3d: LOGIN FAILED, user=[email protected], ip=[::ffff:192.168.1.22]

    I also notice a chain of more error messages related to amavis:

    Anyone have any ideas?

    postfix is unable to access the database, that is why. Please double check your account details for the mail_admin user.

    mail_admin

    I have no issues with logging in to the database using the username mail_admin via php so I don't believe it is a rights issue. I have reverified all created .cf and all are pointed towards mail_admin with the correct password.

    how do I check with SQL commands to verify...I am new to linux and to SQL

    well I think I found the problem, just not sure how to fix it.

    When I looked a little closer in phpmyadmin, I noticed that mail_admin is actually mail_admin@localhost
    Everything in postfix points to 127.0.0.1

    Could this be the cause?
    If so how do I go about fixing it.

    Reloaded/now Have Different Errors

    So I scrapped the install and started over:
    Got everything loaded up. but still have issues. here is an excerpt from my maillog file

    Feb 18 19:10:58 adsl-75-18-14-103 authdaemond: failed to connect to mysql server (server=localhost, userid=mail_admin): Access denied for user 'mail_admin'@'localhost' (using password: YES)
    Feb 18 19:10:58 adsl-75-18-14-103 pop3d: LOGIN FAILED, user=[email protected], ip=[::ffff:75.18.14.103]
    Feb 18 19:10:58 adsl-75-18-14-103 pop3d: authentication error: Input/output error


    I looked at /etc/authlib/authdaemonrc it looks like this:

    ##NAME: authmodulelist:2

    authmodulelist="authmysql"
    #authmodulelist="authuserdb authpam authpgsql authldap authmysql authcustom authpipe"

    ##NAME: authmodulelistorig:3
    authmodulelistorig="authuserdb authpam authpgsql authldap authmysql authcustom authpipe"

    ##NAME: daemons:0
    daemons=5

    ##NAME: authdaemonvar:2
    authdaemonvar=/var/spool/authdaemon

    ##NAME: DEBUG_LOGIN:0

    DEBUG_LOGIN=0

    ##NAME: DEFAULTOPTIONS:0

    DEFAULTOPTIONS=""

    ##NAME: LOGGEROPTS:0

    LOGGEROPTS=""

    I also included /etc/authlib/authmysqlrc:
    MYSQL_SERVER localhost
    MYSQL_USERNAME mail_admin
    MYSQL_PASSWORD ########
    MYSQL_PORT 0
    MYSQL_DATABASE mail
    MYSQL_USER_TABLE users
    MYSQL_CRYPT_PWFIELD password
    #MYSQL_CLEAR_PWFIELD password
    MYSQL_UID_FIELD 5000
    MYSQL_GID_FIELD 5000
    MYSQL_LOGIN_FIELD email
    MYSQL_HOME_FIELD "/home/vmail"
    MYSQL_MAILDIR_FIELD CONCAT(SUBSTRING_INDEX(email,'@',-1),'/',SUBSTRING_INDEX(email,'@',1),'/')
    #MYSQL_NAME_FIELD
    MYSQL_QUOTA_FIELD quota

    So stumped again. I am going to go back and look at the different postfix files and make sure that it isn't any of those.

    Now its a rights issues. I can no way log in to the sql server with mail_admin.

    How do I fix it?
     
  7. tmaleshafske

    tmaleshafske New Member

    The rights issue is fixed...not the ideal way either, but fixed. I still need to know how to update the rights of mail_admin.

    Now I'm having two additional errors:

    1. user can't connect to mail box maillog shows the following error:
    Feb 18 21:39:12 males001 pop3d: Connection, ip=[::ffff:75.18.14.103]
    Feb 18 21:39:18 males001 pop3d: chdir maleshafske.com/test/: No such file or directory

    Feb 18 21:40:23 males001 postfix/qmgr[2820]: warning: connect to transport males001.maleshafske.com: No such file or directory

    2. incoming mail doesn't get to vmail directory it just gets tied up at my dns host that I have as a relay. Here is the maillog report for an email i sent to [email protected] from yahoo:

    Both instances point to an issue with postfix, also when i look /home/vmail/ there are no directories or mail box.

    further up is my postconf.cf

    Well I am a dumb ass....to all you newbies out there don't make the same mistake I did.

    In my mail database I had an entry in transport that was equal to the transport in postfix i.e.
    males001.maleshafske.com which were looping back or canceling each other out however you want to look at it.

    As far as the other problem with the mailboxes another reboot resolved the issue.

    It is working great now.
