Dovecot configuration woes

I've been trying to set up a small office server using the SOHO Postfix guide in the arch wiki here: http://wiki.archlinux.org/index.php/SOHO_Postfix
I've managed to massage most of the kinks out of it but one issue still baffles me. When I attempt to login to dovecot via telnet I get an "OK logged in" message immediately followed by connection closed by foreign host.
/var/log/mail.log:

Dec 31 09:21:40 ArchLAMP dovecot: auth(default): new auth connection: pid=3387

Dec 31 09:21:49 ArchLAMP dovecot: imap-login: Login: user=<test1@domain.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured

Here's my /etc/dovecot.conf

protocols = imap imaps
auth_verbose = yes
auth_debug = yes
auth_debug_passwords = yes
ssl_disable = yes
ssl_cert_file = /etc/ssl/certs/server.crt
ssl_key_file = /etc/ssl/private/server.key
first_valid_uid = 5000
first_valid_gid = 5000
listen = *
disable_plaintext_auth = no
auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@
namespace private {
    separator = .
    prefix = INBOX.
    inbox = yes
    hidden = yes
}
protocol imap {
    imap_client_workarounds = delay-newmail outlook-idle tb-extra-mailbox-sep
}
protocol lda {
    postmaster_address = postmaster@domain.com
    hostname = ArchServer
    sendmail_path = /usr/sbin/sendmail
}
auth default {
    passdb sql {
        args = /etc/dovecot/dovecot-sql.conf
    }
    userdb sql {
        args = /etc/dovecot/dovecot-sql.conf
    }
}

and /etc/dovecot/dovecot-sql.conf

driver = mysql
connect = host=localhost dbname=postfix user=postfix password=password
default_pass_scheme = CRYPT

password_query = SELECT password FROM mailbox WHERE username = '%u' AND active = '1'
user_query = SELECT maildir AS mail, 5000 AS uid, 5000 AS gid, "/srv/vmail" AS home FROM mailbox WHERE username = '%u' AND active = '1'

I haven't the foggiest idea how to procede. Thanks in advance for help.

Re: Dovecot configuration woes

Hi,

it seems that setting a "mail_location" would fix this.

In my dovecot.conf I don't have any namespaces, so I have a global defined mail_location:

mail_location = maildir:/var/mailboxes/%u/

Note that my mailboxes directory is /var/mailboxes, yours may vary. If you followed the guide from the wiki, your mailboxes directory should be /home/vmail (check main.cf from Postfix).

You could also set this location inside your namespace block (by using 'location = ...) :-)
