    Hi

    Here is my environment:
    Red Hat Enterprise Linux Server release 5.7 (Tikanga)
    postfix-2.9.1-1.rhel5
    dovecot 1.0.7

    I
    want to config a complete postfix-dovecot mail server. First I
    configured postfix to use procmail, its default LDA and dovecot for pop3
    and imap. I didn't changed main.cf a lot, just myhostname and a few
    other properties. I didn't set home_mailbox. About dovecot.conf here is
    the output of dovecot -n :

    1.0.7: /etc/dovecot.conf

    log_path: /var/log/dovecot.log
    protocols: imap pop3
    login_dir: /var/run/dovecot/login
    login_executable(default): /usr/libexec/dovecot/imap-login
    login_executable(imap): /usr/libexec/dovecot/imap-login
    login_executable(pop3): /usr/libexec/dovecot/pop3-login
    mail_debug:
    yes
    mail_executable(default): /usr/libexec/dovecot/imap
    mail_executable(imap): /usr/libexec/dovecot/imap
    mail_executable(pop3): /usr/libexec/dovecot/pop3
    mail_plugin_dir(default): /usr/lib64/dovecot/imap
    mail_plugin_dir(imap): /usr/lib64/dovecot/imap
    mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3
    auth default:
      mechanisms: plain login
      passdb:
        driver: pam
      userdb:
        driver: passwd

    As
    you can see mail_location is not set. At this time everything was OK
    and working. I was able to send email using SquirrelMail and
    thunderbird. I got two users, user1 and user2, in my linux machine and
    when I sent an email from user1@software.com to user2@software.com the
    sent mail was saved in /home/user1/mail/Sent and the received email was
    in /var/mail/user2. The log file for dovecot had entries like this for
    user1 and user2:

    dovecot: Oct 14 14:44:52 Info: IMAP(user1):
    maildir: couldn't find root dir
    dovecot: Oct 14 14:44:52 Info: IMAP(user1): mbox: root exists (/home/user1/mail)
    dovecot: Oct 14 14:44:52 Info: IMAP(user1): mbox: INBOX exists (/var/mail/user1)
    dovecot: Oct 14 14:44:52 Info: IMAP(user1): mbox: root=/home/user1/mail, index=/home/user1/mail, inbox=/var/mail/user1

    At this point I tried to change the LDA from procmail to dovecot by the following settings:

    I added/changed the following in the main.cf:

    mailbox_command = /usr/libexec/dovecot/deliver
    dovecot_destination_recipient_limit = 1
    virtual_mailbox_domains = software.com
    virtual_transport = dovecot

    I added the following in the master.cf:

    dovecot   unix  -       n       n       -       -       pipe
      flags=DRhu user=vmail:vmail
    argv=/usr/libexec/dovecot/deliver -f ${sender} -d ${recipient}

    But
    it didn't work. When I send email from from user2 to user1 the sent
    email is correctly saved in /home/user2/mail/Sent but it seems that
    user1 doesn't receive the incoming email. dovecot.log had entries like
    the following:

    dovecot: Oct 14 14:54:04 Info: imap-login: Login:
    user=<user1>, method=PLAIN, rip=::ffff:172.27.7.8,
    lip=::ffff:172.16.100.183, TLS
    dovecot: Oct 14 14:54:04 Info: IMAP(user1): Effective uid=504, gid=504, home=/home/user1
    dovecot: Oct 14 14:54:04 Info: IMAP(user1): maildir: access(/home/user1/Maildir, rwx): failed: No such file or directory
    dovecot: Oct 14 14:54:04 Info: IMAP(user1): maildir: couldn't find root dir
    dovecot: Oct 14 14:54:04 Info: IMAP(user1): mbox: root exists (/home/user1/mail)
    dovecot: Oct 14 14:54:04 Info: IMAP(user1): mbox: INBOX exists (/var/mail/user1)
    dovecot: Oct 14 14:54:04 Info: IMAP(user1): mbox:
    root=/home/user1/mail, index=/home/user1/mail, inbox=/var/mail/user1

    Setting
    home_mailbox = Maildir/ in main.cf and mail_location =
    maildir:~/Maildir in dovecot.cf didn't help. I have been googling and
    reading and testing for 4 or 5 days for this but there was no chance.
    Now, I am stuck and any help would be really really appreciated.

    Regards,
    Ferez

    This forum is for PostfixAdmin, a web interface to manage mailboxes and aliases using a database (well, a bit more, that's only the short summary).

    For dovecot questions, better ask on the dovecot mailinglist or IRC channel (see http://dovecot.org/support.html ) - you'll get better help there.
