编辑 – 附加配置信息(一些重叠)

service auth {
# auth_socket_path points to this userdb socket by default. It's typically
# used by dovecot-lda,doveadm,possibly imap process,etc. Its default
# permissions make it readable only by root,but you may need to relax these
# permissions. Users that have access to this socket are able to get a list
# of all usernames and get results of everyone's userdb lookups.
unix_listener auth-userdb {
  mode = 0644
  user = vmail
  group = vmail
}
 
# Postfix smtp-auth
unix_listener /var/spool/postfix/private/auth {
  mode = 0660
  user = postfix
  group = postfix
}
 
# Auth process is run as this user.
#user = $default_internal_user
user = dovecot
}

问题

我非常仔细地遵循了教程,仅更改了一些小问题.
我到达了“测试邮件传递”并运行了echo test | mail test@chefdovecot.com

由于发现/ var / vmail没有显示任何内容,因此邮件未到达.

在服务器syslog中,存在以下错误：

postfix/pickup[16842]: 019023A06AB: uid=1000 from=<vagrant>

“连接被拒绝”错误应该是我正在攻击的错误,对吧？我在很多地方搜索过,以了解这里发生了什么,但没有发现任何有用的东西.

任何人都可以提供任何线索或见解吗？解决方案会很棒,但我很乐意接受一些新的想法来尝试.
