The topic about http://xmailforum.homelinux.net/index.php?showtopic=2159 was nice but it introduce additional step before Dovecot can see changes in XMail user database - administrator must run xmail2dovecot.php to update dovecotusers.tab which could be a problem if users are managed via PHPXMail, for example. Another solution is to use pam_pop3 module to authenticate users against XMail directly.

1. Install pam_pop3
Download source from ftp://ftp.freebsd.org/pub/FreeBSD/distfiles/pam_pop3-1.0.tar.gz unpack and run make. Copy resulted pam_pop3.so to /lib/security directory.
In case make fails with many syntax errors - you need PAM development headers to be installed. Install them from your distribution package, something like pam-devel...rpm (RedHat/etc.) or libpam0g-dev (Debian).
If you are on *BSD then use security/pam_pop3 port.

2. Dovecot and XMail non-root UID setup
Perform necessary steps to run XMail and Dovecot under single non-root UID as described in above mentioned topic.
These non-root UID guides are ok too - http://sandbox.rulemaker.net/ngps/132 and http://www.spectr.org/sergey/HowTo-Chrooted-XMail.html (no need to chroot).

3. Additional configuration
Dovecot config:

CODE

first_valid_uid = 10
auth = default
auth_mechanisms = plain
auth_passdb = pam
auth_userdb = static uid=108 gid=108 home=/var/spool/xmail/domains/%d/%n/Maildir
auth_user = root
login = imap
protocols = imap
default_mail_env = maildir:/var/spool/xmail/domains/%d/%n/Maildir

uid=108 is UID Dovecot and XMails runs under.

Put into /etc/pam.d/dovecot:

CODE

auth required pam_pop3.so hostname=localhost
account required pam_permit.so

hostname=localhost is where XMail is running. There is also port= parameter to change POP3 port - you could skip XMail pop3 20110 port mapping with Iptables, enable Dovecot POP3 service and run your mail server frontend services entirely by Dovecot, in that case you need port=.
