mail()这些函数的共同之处，都是需要进行网络传输，并且是函数所在服务器a作为客户端与对方服务器b进行网络传输。这就是牵涉到，找到对方服务器b，和对方服务器b进行连接，传输信息！那么问题就存在3个地方1. 寻找b时间过长，这就要看a的dns解析的时间，例如在a上执行nslooup，ping b等，看这个时间的长度2. 连接的问题，拿fsockopen来说，执行前记录一个时间，执行后记录一个时间，验证下连接的时间，另外可以更改fsockopen的超时连接的时间，比如设定1秒，看是否有变化3. 传输的问题，这才是我们常说的“网络问题”,这个也仅仅会发生在网络丢包严重的情况所以不仅仅是你说的网络没有问题，网络就真的没有问题了，以上的措施你做了吗？
