Google 计算 VM 实例上的 WHM/cPanel 端口 25 上的 EXIM
EXIM on Port 25 from WHM/cPanel on a Google Compute VM Instance
我已经在 Google 计算 VM 实例上设置了 WHM/cPanel 的试用安装，它比我在使用 RackSpace 的不同且更昂贵的专用服务器。
但是（经过长时间的挖掘）我发现 Google 不允许他们的虚拟机在端口 25 上发送邮件。

WHM支持说：
"If google VM is blocking port 25, there are no changes in WHM that will allow you to work around this. Exim MUST use port 25 to send/receive mail. The only other option would be to use a smart host, which would route the mail out through another server. This would require a second server configured for you to relay through it."
还有其他解决办法吗？两台服务器会使我的成本比现在更高，并且失去了从 Rackspace 迁移到 Google Compute 对我来说的主要好处之一。
