Linux 后缀-状态=已反弹（未知用户“myuser”）

我正在配置Postfix，通过telnet和SMTP验证时，我得到了状态已反弹错误，未知用户：

错误日志：

“myuser”已存在，但具有完整域名：myuser@mydomain.com.

用户验证：

 postmap -q myuser@mydomain.com mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf

virtual_transport = dovecot

输出是：“1”-所以我想它是好的

我的后缀配置：

 postmap -q myuser@mydomain.com mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf

root# postconf -n:
append_at_myorigin = yes
biff = no
config_directory = /etc/postfix

谢谢您的帮助。

您已经添加了

mydestination=mydomain.com

，因此将在

本地收件人地图中搜索
mydomain.com
的有效用户。从日志行可以非常清楚地看到，选择了
local
delivery代理来传递邮件，因为本地域类匹配。请参阅以获取更多帮助

修改main.cf，如下所示

#/etc/postfix/main.cf
mydestination = 
# set to localhost localhost.$mydomain or remove mydomain.com for now
# Ensure that postmap -q mydomain.com mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf is returning mydomain.com and 
# postmap -q myuser@mydomain.com mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf succeeds

对于其他人，当我设置mydestination=mydomain.com时。
Postfix show警告不要在mydestination和virtual_mailbox_域中同时列出域mydomain.com。所以我将其设置为relayhost=mydomain.com

My postfix版本：3.1.0（postconf-d | grep mail_版本）
打开
/etc/postfix/main.cf
，查找
mydestination
字段并将其值更改为以下值

mydestination = localhost, localhost.localdomain

不要忘记运行
sudo postfix reload
之后
在/var/postfix/main.cf中使用以下设置

myorigin = localhost
myhostname = <your_host_name>
mydestination = localhost.$mydomain, localhost, localhost.localdomain

这对我来说很有效，除了返回
postmap/etc/postfix/virtual
，它返回了
postmap:fatal:open/etc/postfix/virtual:没有这样的文件或目录
——对于meI来说仍然可以，因为她正在配置AWS SES与SMTP的使用，并且注意到本地传递。这解决了我的问题。它太奇怪了，AWS文档中没有提到它（也许我只是没有找到它…）。谢谢我没有/etc/postfix/mysql-*文件，但更改mydestination对我很有用。谢谢
