当目的地是我的域名时 POSTFIX 会弹回

我使用提供商邮件托管来发送电子邮件。在我的 Web 服务器上，我还运行并配置了 Postfix。这是我的主配置文件

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
append_dot_mydomain = yes
readme_directory = no
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
myhostname = 2-5-8.bih.net.ba
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = bhcom.info, 2-5-8.bih.net.ba, localhost.bih.net.ba, localhost
relayhost = 
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_command = 
mailbox_size_limit = 10485760
recipient_delimiter = +
inet_interfaces = 80.65.85.114

当我尝试向托管域名发送电子邮件时，每封邮件都会因此错误而被退回：

但是，当我尝试访问 @gmail.com 时，它发送消息没有问题，以下是日志。可能是什么问题？

答案1

嗯，日志是这么说的：

Nov  4 20:38:34 2-5-8 postfix/local[990]: 1492A3E0C6C: to=<[email protected]>, relay=local, delay=0.12, delays=0.08/0.01/0/0.04, dsn=5.1.1, status=bounced (unknown user: "info")
Nov  4 20:38:34 2-5-8 postfix/local[990]: 28ED53E0C6D: to=<[email protected]>, relay=local, delay=0.06, delays=0.03/0/0/0.02, dsn=5.1.1, status=bounced (unknown user: "razvoj")

您没有本地用户info，也没有razvoj本地投递可以投递邮件。如果我理解您的帖子没有错的话，您确实想从那台机器发送邮件，但这不是您想要接收和阅读邮件的邮件服务器，对吗？

如果正确的话，只需删除bhcom.info它mydestination，一切都会好起来。

一些背景知识：mydestinationPostfix 认为列出的每个主机名都是本地的，然后 itr 会尝试将邮件发送给该本地用户，但在您的情况下，该本地用户并不存在。

还要确保您拥有所需的所有软件包。我在 main.cf 中正确设置了中继主机，但直到我执行此操作（在 Ubuntu 14.04 上）时，中继才显示为无：

apt-get install mailutils libsasl2-2 ca-certificates libsasl2-modules

不确定为什么这样可以修复它。以上内容来自 postfix 转发的 HOWTO，网址为easyengine.io。
