Dovecot is an open source IMAP/POP3 server for *nix Operating Systems
More info at: http://www.dovecot.org
Documentation at: http://wiki.dovecot.org

NOTE Dovecot's default UIDL format isn't compatible with Outlook 2003 to fix set this setting as follows:

pop3_uidl_format = %08Xu%08Xv

Example dovecot.conf

# Protocols we want to be serving
protocols = imap imaps pop3 pop3s

# Listen on all IPv4 Interfaces
listen = *

# Kill all IMAP and POP3 processes when Dovecot master process shuts down
shutdown_clients = yes

# Disable SSL/TLS support.
ssl_disable = no

# SSL Certificate info
ssl_cert_file = /etc/pki/tls/certs/server.crt
ssl_key_file = /etc/pki/tls/certs/server.key

# Mailbox locations
default_mail_env = maildir:/usr/local/virtual/%u

# IMAP specific settings
protocol imap {
        listen = *:143
        ssl_listen = *:993
}

# POP3 specific settings
protocol pop3 {
        listen = *:110
        ssl_listen = *:995
}

# Authentication processes exectuable
auth_executable = /usr/libexec/dovecot/dovecot-auth
 
# Authentication Settings
auth default {

  # Authentication Mecahnisms
  mechanisms = plain login digest-md5 cram-md5 gssapi

  # Path for SQL configuration file
  passdb sql {
   args = /etc/dovecot-sql.conf
  }

  # Path for SQL configuration file
  userdb sql {
    args = /etc/dovecot-sql.conf
  }

  # User to use for the process. This user needs access to only user and password databases, nothing else.
  user = root
 
 # Make dovecot-auth available to Postifx for SASL authentication
 socket listen {
   client listen {
     path = /var/spool/postfix/private/auth
     mode = 0660
     user = mail
     group = mail
   }
 }

}

NOTE:
path = /var/spool/postfix/private/auth in dovecot.conf should match smtpd_sasl_path = /var/spool/postfix/private/auth in postfix's main.cf
See Postfix & Dovecot-Auth for reference.

Example dovecot-sql.conf

# Database driver: mysql, pgsql, sqlite
driver = mysql

# Database connection string.
connect = host=localhost port=3306 dbname=mail user=mail password=********

# Default password scheme
default_pass_scheme = PLAIN CRAM-MD5 DIGEST-MD5 MD5-CRYPT NTLM

# Password Query
password_query = SELECT password FROM users WHERE username = '%u'

# User Query
user_query = SELECT maildir, uid, gid FROM users WHERE username = '%u'
