    Me again!
    I installed ISPConfig 3, followed this tutorial: https://www.howtoforge.com/tutorial...l-pureftpd-bind-postfix-doveot-and-ispconfig/
    Installation went like a charme. After adding a lot of e-mail accounts to this server and wondering why I can't connect, I found this entry in the e-mail error log:

    Code:
    Jun 11 08:18:27 server100 dovecot: imap: Error: Internal auth failure (client-pid=11084 client-id=1)
    Jun 11 08:22:39 server100 dovecot: auth-worker(13833): Error: sql([email protected],79.198.200.121): Invalid UID value '-1'
    Jun 11 08:22:39 server100 dovecot: auth-worker(13833): Error: sql([email protected],79.198.200.121): Invalid GID value '-1'
    Jun 11 08:22:39 server100 dovecot: auth: Error: sql([email protected],79.198.200.121,<br/BW/w0Ea5Pxsh5>): Invalid UID value '-1'
    Jun 11 08:22:39 server100 dovecot: auth: Error: sql([email protected],79.198.200.121,<br/BW/w0Ea5Pxsh5>): Invalid GID value '-1'
    So, none of the entered e-mail accounts were created on the server. The directory of /var/vmail is empty.
    How can I fix that and how can I get those e-mail accounts being created afterwards? How can I prevent this situation on installation?

    The output of id -g vmail:
    Code:
    [email protected]:/# id -g vmail
    5000
    
    and of id -u vmail:
    Code:
    [email protected]:/# id -u vmail
    5000
    
    Seems to be okay... :confused:
    The dir /var/vmail is also owned by vmail/vmail.

    It seems that this error affects only ISPConfig 3.1!
    I've done a perfect server setup with Debian Jessie. But iinstead of downloading ISPConfig v3.0 I used v3.1.
    All is fine with Debian Jessie and ISPConfig 3.0 but with 3.1 the same error occured.

    I'll add it to the bugtracker. But my Jesse + ISPConfig 3.1 server has no mail issues

    I did a fresh install with latest from stable-3.1 branch and there arc no issues with mailuser uid's on the server. Maybe you disabled some php functions which prevented ispconfig from working.

    Never mind, I found the issue. You must have enabled the cluster email uid/gif mapping feature.

    There are 3 possibilities that can have caused your issue:

    1) You did not wait 60 seconds until the server cronjob has written the new uid's.
    2) The server.sh cronjob in ispconfig was not running at all or cron on your server is broken.
    3) You enabled the uid/gid mapping feature on a multiserver system.

    So, how do we solve this as i have the same problem, i've installed 3.1 to and would love to use it. 26mails in que and growing. Next to that i get "(mail transport unavailable)" as well, is it related to this error or is it something else.

    So did you enable the "Use Websites Linux uid for mailbox" setting which is off by default and can cause this error?

    @till:
    Wondering why this error occured two times. On both installations I followed your tutorials step by step.
    It can't be a broken cron and I do not running a multiserver setup. The only thing what could happened, I didn't wait 60 seconds...
    I'll try a new Ubuntu setup again later.

    @includes08:
    For further information, please post your main.cf and follow the steps in the first post by till in this forum.

    Code:
    [email protected]:~# id -g vmail
    5000
    [email protected]:~# id -u vmail
    5000
    
    I don't even have a clue where this option is. I did 3 or 4 installs and still nothing.

    found the option, and it is indeed just disabled by default.

    Use Websites Linux uid for mailbox
    only in single web and mail-server-setup

    The uid/gid function which you used works like this: The uid and gid is set to -1 by the interface, the server plugin then tries to resolve the uid and gid locally to match the uid and gid of a website with the same domain name, If it finds a website, then the uid and gid of the website is set, if it does not find a site, the value 5000 is used. It takes up to 60 seconds until the server cron runs, and the mailbox can not be used before the cronjob has run. Personally I would never use this function on a server and that's why it is off by default, it is against the paradigm of a virtual mail system that ISPConfig uses, it is not compatible with multiserver systems, it is likely to break your mailboxes when you have issues with a related website and it allows an attacker of a hacked website to access your emails.

    till Super Moderator Staff Member ISPConfig Developer

    Ok, so ensure that the setting is off. Which value do you have for uid and gid of the mail account in the mail_user table ?
     
  14. includes08

    includes08 New Member

    I don't have a multiserver system yet (if you mean clustering with that). I'm planning to but the option is still of cause, its default like that i didn't even know about that option before.

    Please answer my question about the uid and gid in the database.

    Jun 14 11:47:38 web1 dovecot: imap: Error: Internal auth failure (client-pid=41009 client-id=1)
    I guess by seeing this its -1,
    how do i look it up in the database exactly?

    Please enable debugging under System > server config and then run:

    /usr/local/ispconfig/server/server.sh

    and post the output.

    Additionally, post the output of:

    ls -la /usr/local/ispconfig/server/plugins-enabled/

    Thats both ok. Now look into the dbispconfig database, the records in mail_user table should have the correct uid now.

    5000 / 5000 but still nothing works, i can't send mail i can't receive mail, and my que gets bigger and bigger. Is there a way that you could take a look over teamviewer if possible? or direct access.
