dovecot配置虚拟用户

添加一个用户

useradd vuser
echo "vuser" |passwd --stdin vuser

查看uid, gid

cat /etc/passwd | grep ^vuser -w|awk -F: '{print $3}'
500

假设上面查到的uid, gid为500, 修改/etc/dovecot/conf.d/10-mail.conf

mail_uid = 500
mail_gid = 500
mail_location = mbox:/home/vuser/var/mail/%u

修改/etc/dovecot/conf.d/auth-passwdfile.conf.ext

内容如下:

userdb passwd-file {
  driver = passwd-file
  args = /etc/dovecot/users
}
passdb passwd-file {
  driver = passwd-file
  args = /etc/dovecot/users
}

直接找开/etc/dovecot/users文件添加即可

passdb文件格式

user:password

使用doveadm加密密码。我用的是PLAIN加密方式, 添加一个test的虚拟用户，密码为123456

doveadm pw -u test -p 123456 -s PLAIN
{PLAIN}123456

在/etc/dovecot/users中添加用户

test:{PLAIN}123456

Error: user test: Couldn't drop privileges: Mail access not allowed for root 出现这个错误说明不允许root访问，所以需要修改mail_uid, mail_gid
