    I tried to reinstall ispconfig with courier, and now I can't receive mails. Imap authentification works, but when I check in /var/log/mail.log, I get this:

    Jun 16 19:33:42 hostname postfix/pipe[1807]: 9EC7169CC: to=<user@domain.tld>, relay=maildrop, delay=2398, delays=2398/0.04/0/0.01, dsn=4.3.0, status=deferred (temporary failure. Command output: ERR: authdaemon: s_connect() failed: Permission denied /usr/bin/maildrop: Unable to change to home directory. )
    What am I missing? The Maildir directories exist and have the good owner (vmail:vmail) and rights.

    Please install your server exactly as described in the ispconfig 3 perfect setup guide for your linux distribution.

    I Did.

    I reinstalled again, it seems the bug occurs when using ispconfig's system->serverconfig->mail panel to change directories (changed /var/vmail to /home/vmail, as it is on a different partition).
    The imap server reads the files from the new location, but it seems maildrop still wants to put them in /var/vmail

    I tried to change vmail user's home directory, but it doesn't work...

    The setting for the mail directory can not be changed, this is not supported. You will have to change it back.

    I don't have room on the system partition, what should I do then? And why is the mail folder editable in ispconfig's interface if you can't change it?

    edit: It seems to work now, but when I send mail to mailboxes that doesn't exit, the Maildir folders are created.

    Repartition your system.

    No, it will not work properly.

    I'd love to, but webservers are not often computers you own and keep in your room :D

    I read maildrop's documentation here, and it is told in the delivery mode section that maildrop will look into vmail user's home directory.

    Now, I'm reading the .mailfilter file created by ispconfig, and it seems it simply creates the maildir if it doesn't exist.

    Which program checks if the user exists? It is Postfix, before giving it to maildrop (but why would Postfix be affected by vmail's directory location ?), or is there an authentification mechanism in maildrop that connects to the database?

    ( also changed /etc/postfix/ virtual_mailbox_base to /home/vmail )

    Do you chown the file??

    # chown -R vmail:vmail /home/vmail

    wouldn't it be simplier to create symlink? like writing

    Postfix will not accept emails for any non existing users in a default ispconfig setup, maybe you changed something there or you configured postfix before you installed ispconfig for a different setup.

    I reinstalled all from scratch with the install guide (ubuntu 9.04), and tried it with all the default directories.

    I still have the same problem, it seems postfix doesn't check if a user exists when receiving mail and creates all the maildirs.

    Could it be that postfix doesn't connect to the mysql database? all the /etc/postfix/mysql_virtual_*.cf generated by ispconfig seem correct. How could I see if postfix correctly gets the virtual user data?

    Any ideas?

    Please post the content of your file and also an excerpt of the mail log that shows the receiving process for an existing email account and also for a non existing account that goes trough.

    Is "domain.tld" the same that you masked as <hostname> in the file or is domain.tld in the /etc/mailname file?
  15. gring

    gring HowtoForge Supporter

    <hostname> is the same than in /etc/hostname and /etc/mailname (it's the main name given to the server by the provider)

    domain.tld is one of the domains hosted on the server with ispconfig.

    And domain.tld is setup in ispconfig only as mailbox domain and not as relay domain?

    It's only set as an email domain.

    I've set mysql to logging mode, and it does receive the requests from postfix.
