我正在使用 postfix 和 gmail 小型企业应用程序
它似乎可以很好地将电子邮件发送到外部域，但在尝试发送到同一域的电子邮件时不起作用
例如[电子邮件保护]发送至[电子邮件保护]没问题但是，[电子邮件保护]不发送给[电子邮件保护]
问题是我的 postfixc 配置文件是否有问题？

# line of that file to be used as the name. The Debian default

答案1
如果我理解正确的话，mysite.com 的邮件由 Google Apps 处理。这样对吗？
如果是这样，您的列表中就不应该有 mysite.com mydestination。postfix 文档，该列表中的条目将在本地传送，而不是中继到其他邮件系统。
