主配置文件 /usr/local/etc/dovecot/dovecot.conf

# Protocols we want to be serving.
protocols = imap pop3 lmtp# A comma separated list of IPs or hosts where to listen in for connections.
# "*" listens in all IPv4 interfaces, "::" listens in all IPv6 interfaces.
# If you want to specify non-default ports or anything more complex,
# edit conf.d/master.conf.
listen = *

认证文件 /usr/local/etc/dovecot/conf.d/10-auth.conf

disable_plaintext_auth = no
auth_mechanisms = plain login
#!include auth-system.conf.ext
!include auth-sql.conf.ext

ssl配置文件 /usr/local/etc/dovecot/conf.d/10-ssl.conf 设置为no，注释掉ssl_cert，如要启用，则要创建ssl_key

ssl = no
#ssl_cert = </etc/ssl/certs/dovecot.pem
#ssl_key = </etc/ssl/private/dovecot.pem

日志文件 /usr/local/etc/dovecot/conf.d/10-logging.conf 指定的日志文件记得给权限,我指定的777

log_path = /var/log/dovecot.log
auth_debug = yes
mail_debug = yes

邮箱配置 /usr/local/etc/dovecot/conf.d/10-mail.conf uid和gid是开始建立的postfix的id

mail_home = /home/xmail/%d/%n
mail_location = maildir:~/Maildir
first_valid_uid = 1010
first_valid_gid = 1010

配合postfix /usr/local/etc/dovecot/conf.d/10-master.conf

unix_listener auth-userdb {mode = 0600user = tmailgroup = tmail}
# Postfix smtp-authunix_listener /var/spool/postfix/private/auth {mode = 0666user = postfixgroup = postfix}

指定sql配置文件 /usr/local/etc/dovecot/conf.d/auth-sql.conf.ext

passdb {driver = sql# Path for SQL configuration file, see example-config/dovecot-sql.conf.extargs = /usr/local/etc/dovecot/dovecot-sql.conf.ext
}
userdb {driver = sqlargs = /usr/local/etc/dovecot/dovecot-sql.conf.ext
}

mysql配置文件 /usr/local/etc/dovecot/dovecot-sql.conf.ext

driver = mysql
connect = host=localhost dbname=postfix user=root password=123456
default_pass_scheme = MD5
password_query = \SELECT username,password \FROM mailbox WHERE username = '%u' AND active = '1'
##下面的1020 是指邮件存储目录的uid gid
user_query = \SELECT maildir,1020 AS uid,1020 AS gid \FROM mailbox WHERE username = '%u' AND active = '1'

邮箱目录 /usr/local/etc/dovecot/conf.d/15-mailboxes.conf
