我按照本指南使用 postfix、dovecot 和 mysql 使用 vhosts 设置电子邮件。当我向邮件服务器发送电子邮件时，它会被退回，并且我收到以下消息/var/log/mail.info：

11 月 27 日 14:39:21 myserver postfix/lmtp[21637]: B999E1E86A: to=<[email protected]>, orig_to=, relay=example.com[private/dovecot-lmtp], delay=0.14, 延迟=0.12/0/0.01/0.01, dsn=5.1.1, status=bounced (host example.com[private/dovecot-lmtp] said: 550 5.1.1 <[email protected]> 用户不存在: [email protected] (回复 RCPT TO 命令))

出于某种原因，我看到它正在将 [email protected] 转发到 [email protected]。

关于它应该如何工作，我不是这里的专家，但我认为这有两个问题。

  1. 用户名被数字 1 替换
  2. 主机名被添加到域名的前面（不确定这是设计使然还是错误）

是什么导致了我的问题，我能做些什么来解决它？

完全错误

根据评论，这是我的完整错误：

我正在尝试从letsencrypt获得roundcube、dovecot、postfix和证书，以便在Debian 9上协同工作。

我使用 apt-get 命令安装了 roundcube。

尝试登录圆形立方体时，它需要很长时间才能显示“正在加载...”，但随后并没有让我登录。屏幕上的错误显示Connection to storage server failed。查看圆形立方体错误日志，我收到以下错误：

IMAP Error: Login failed for [email protected] from 192.0.2.10. Empty startup greeting (localhost:143) in /usr/share/roundcube/program/lib/Roundcube/rcube_imap.php on line 193 (POST /?_task=login&_action=login)

运行/etc/init.d/dovecot status我得到以下信息：

dovecot[29431]: imap-login: Disconnected (no auth attempts in 60 secs): user=<>, rip=::1, lip=::1, TLS handshaking: SSL_accept() syscall failed: Success, session=<azgn6uptGtgAAAAAAAAAAAAAAAAAAAAB>

我的 config.inc.php 中有以下内容：

$config['default_host'] = 'tls://localhost';

和

$config['imap_conn_options'] = array(
   'ssl'         => array(
     'verify_peer'  => false,
     'verify_peer_name' => false,
    ),
);

$config['username_domain'] = '%d';

以及我的 dovecot 10-ssl.conf 文件中指定的以下内容：

ssl = required

ssl_cert = </etc/letsencrypt/live/example.com/fullchain.pem
ssl_key = </etc/letsencrypt/live/example.com/privkey.pem

我的 10-master.conf 文件中还有以下内容：

service imap-login {
  inet_listener imap {
    port = 0
  }
  inet_listener imaps {
    port = 143
    ssl = yes
  }
}
service pop3-login {
  inet_listener pop3 {
    port = 0
  }
  inet_listener pop3s {
    port = 995
    ssl = yes
  }
}

如果我这样做，telnet localhost 143我会得到：

Trying ::1...
Connected to localhost.
Escape character is '^]'.

我不确定我是否应该得到更多。

坦率地说，我不确定我的问题出在哪里，或者还有什么要调查的。为什么我无法登录roundcube，我还应该在哪里检查以查明我的问题？

我正在使用以下设置在实验室环境中进行测试：

我有一台安装了 VMware Workstation 12 Pro 的 Windows 10 笔记本电脑。我在运行 Windows Server 2012 R2 的工作站中创建了一个虚拟机。我已经在上面设置了 AD 和 DNS。此服务器的 IP 地址为 192.168.59.129，其 FQDN 为 win2012.ad.example.com。我可以 ping 通机器并且 DNS 工作正常。

我现在正在尝试安装 vCenter Server Appliance 6.5 ，到目前为止没有成功。我正在尝试使用 OVA 文件：VMware-vCenter-Server-Appliance-6.5.0.5200-4944578_OVF10.ova位于 ISO 中。我在阅读了几篇文章后了解到，我首先需要在启动机器之前配置 .vmx 文件。我认为主要原因是我没有完全理解应该放在文件中的设置，特别是 vmdir 设置。我已经尝试了许多不同的设置变体，但似乎仍然没有任何效果。我最近的配置如下所示：

guestinfo.cis.deployment.node.type = "embedded"
guestinfo.cis.appliance.net.addr.family = "ipv4"
guestinfo.cis.appliance.net.mode = "static"
guestinfo.cis.appliance.net.pnid = "vc.ad.example.com"
guestinfo.cis.appliance.net.addr = "192.168.59.194"
guestinfo.cis.appliance.net.prefix = "24"
guestinfo.cis.appliance.net.gateway = "192.168.59.129"
guestinfo.cis.appliance.net.dns.servers = "192.168.59.129"
guestinfo.cis.appliance.root.passwd = "Password#1"
guestinfo.cis.appliance.ssh.enabled = "True"
guestinfo.cis.deployment.autoconfig = "True"
guestinfo.cis.vmdir.password = "Password#1"
guestinfo.cis.vmdir.site-name = "vc"
guestinfo.cis.vmdir.domain-name = "ad.example.com"
guestinfo.cis.ceip_enabled = "False"

我还确保 vc.ad.example.com 正确映射到 DNS 服务器上的 192.168.59.194，包括反向 DNS (PTR) 条目。

服务器开始其初始化例程后，我最终在屏幕上收到此错误：

Failed to start services. Firstboot Error.

我在这里做错了什么？

更新

根据下面的答案，我已将配置设置更改为您在下面看到的内容，但它仍然给我同样的错误：

guestinfo.cis.deployment.node.type = "embedded"
guestinfo.cis.appliance.net.addr.family = "ipv4"
guestinfo.cis.appliance.net.mode = "static"
guestinfo.cis.appliance.net.pnid = "vc.ad.example.com"
guestinfo.cis.appliance.net.addr = "192.168.59.194"
guestinfo.cis.appliance.net.prefix = "24"
guestinfo.cis.appliance.net.gateway = "192.168.59.129"
guestinfo.cis.appliance.net.dns.servers = "192.168.59.129"
guestinfo.cis.appliance.root.passwd = "Password#1"
guestinfo.cis.appliance.ssh.enabled = "True"
guestinfo.cis.deployment.autoconfig = "True"
guestinfo.cis.appliance.ntp.servers = "pool.ntp.org"
guestinfo.cis.vmdir.password = "Password#1"
guestinfo.cis.vmdir.site-name = "mysite"
guestinfo.cis.vmdir.domain-name = "vsphere.local"
guestinfo.cis.ceip_enabled = "False"

还有其他想法吗？

由于将我的服务器升级到最新版本的 Debian，roundcube (1.2.3) 不再工作。事实证明这是因为新版本的 PHP (5.6) 现在检查它是否是一个有效的证书。基于对此的进一步研究，我发现我可以将以下行添加到我的 config.inc.php 文件中：

$config['imap_conn_options'] = array(
    'ssl' => array(
      'verify_peer' => false,
      'verify_peer_name' => false
     )
 );


$config['smtp_conn_options'] = array(
    'ssl' => array(
       'verify_peer' => false,
       'verify_peer_name' => false
     )
 );

我也有以下设置：

$config['default_host'] = 'tls://localhost';

我正在为多个域使用这个圆形立方体安装，所以不想在这里放一个特定的域。我也不想为证书付费，所以想将 verify_peer 设置为 false。

当我尝试登录时，它显示“登录失败”。syslog 给出以下错误：

Feb  8 10:55:19 server1 dovecot: imap-login: Disconnected (auth failed, 1 attempts in 2 secs): user=<office>, method=PLAIN, rip=::1, lip=::1, TLS, session=<D+K0ugdIigAAAAAAAAAAAAAAAAAAAAAB>

我想知道如果应该使用 TLS，这个 method=PLAIN 是否会丢掉东西。

我在 mysql 数据库中使用虚拟用户/域/别名在后端设置了 dovecot/postfix。我尝试向这些地址发送消息，但它们确实被重定向到正确的别名电子邮件地址。所以，据我所知 dovecot 和 postfix 工作正常。

我能做些什么来解决这个问题？

我正在运行带有虚拟用户/别名的 dovecot/postfix 服务器。根据http://www.mailradar.com/openrelay/等工具，我没有任何开放中继。但是，我的系统日志中显示了很多记录，这会导致我认为正在访问不应访问的某些内容。这是我的系统日志的一部分（当然更改了自我识别信息）：
