我对plesk和postfix相当新，所以请耐心等待。我在一个服务器上设置了plesk，多个域已经存在并且呼吸，包括所有工作正常的电子邮件。我的问题来自我添加的新域名，即使用电子邮件的交换而不是本地postfix。所以我为此＆＃34; newdomin.tld＆＃34;停用了后缀。在plesk，但任何时候网站尝试发送电子邮件（PHP联系表格）我从来没有收到测试电子邮件（尽管表格报告成功）。
以下是我在 maillog 中出现的错误：

任何帮助将不胜感激，这是在CentOS 6.6上运行的默认plesk设置（12.0.18 Update＃57）。所有其他电子邮件，webmail，smtp设置似乎适用于所有其他服务器，它就是这个拥有Exchange的服务器。我确实通过codero托管确保我的所有DNS设置在plesk以及我的服务器门户中都是正确的。我知道交换设置正在运行，因为每个人都收到他们的电子邮件我只是无法从域中发送电子邮件到交换服务器。
谢谢！

似乎我在/ etc / postfix / transport和/ var / spool / postfix / plesk / transport文件中有gencom.us smtp：206.225.87.101。一旦被移除的东西再次开始工作。
