配置 dovecat 的 PAM

若从源码安装 dovecot，解压dovecot 源码，安装。安装时注意带上 --with-pam 选项

配置

 

# cp /usr/local/share/doc/dovecot/example-config/dovecot.conf /etc/dovecot/ # 建立dovecot配置文件
# cp -r /usr/local/share/doc/dovecot/example-config/conf.d /etc/dovecot/ # 建立dovecot配置文件的需求文件
# vi /etc/dovecot/dovecot.conf
20 protocols = imap pop3 lmtp # 支持邮局协议
# vi /etc/dovecot/conf.d/10-auth.conf
9 disable_plaintext_auth =  no#允许明文密码验证
# vi /etc/dovecot/conf.d/10-ssl.conf
6 ssl = no # 禁用s
# vi /etc/dovecot/conf.d/10-mail.conf
24 mail_location = maildir:~/Maildir # 邮件存储格式及位置

//  创建PAM认证文件
# vi /etc/pam.d/dovecot


auth    required    pam_nologin.so
auth    include       system-auth
account include   system-auth
sesssion include   system-auth


# dovecot   # 启动服务

 

【注意】在 dovecot 2.0 以后，已经使用 bin/doveadm pw 替换了 bin/dovecotpw

 

测试:

# telnet localhost 110

出现+Ok Dovecot ready.则正确

 

还记得我们上一篇发的一个测试邮件吧… 这里我们就收到了

 

错误总结

1、

错误:

dovecot 启动时 显示 ssl_cert_file:Can't use /etc/ssl/certs/dovecot.pem

解决

// 创建两个文件夹

mkdir –p /etc/ssl/certs/

mkdir –p /etc/ssl/private

进入到源码包解压目录

cd doc

sh mkcert.sh

错误:

telnet 110端口的时候停在Escape character is ‘^]’.

不出现+Ok Dovecot ready.

解决:

预编译时加入参数 –with-pam

yum –y install pam-devel

./configure –sysconfdir=/etc –with-pam –with-mysql

make && make install
