你是想做个web页面弄邮件群发吗？

原因能是:
1 你的邮箱帐号不是VIP的
2 各家邮件服务器提供商对免费邮箱的SMTP处理机制不一样，基本上都有所限制，除了VIP
3 如果有时可以发有时不可以发，那是因为邮件服务器每次都判断发出邮件的地址频率很高或
  是tom.com|sohu.com|163.com...其他邮件服务商的。如果是这样把该邮件判断成垃圾邮件或不受理的邮件解决办法：
  1 申请VIP邮箱，会开通通畅的SMPT，那就可以合法使用了
  2 发邮件时，发出人邮箱地址的@后缀用随机算法(比如是 [email protected]\[email protected]...)构造后再发出，
    就可以解决问题。当然，这样做的毙命是收件人收到邮件后看到的发件人邮箱地址的@???就不是真实的，就说他无法
    直接用该地址给回复邮件！不知道我表达的是否清楚？那还有其他方法:
1 自己去了解底层的邮件协议,像FOXMAIL那样做，内置邮件服务系统
2 自己构建邮件系统，第3方的
3 就是上面说的：@地址混淆法
  适用于网站，因为收件人一般不会给网站回邮件，如果你要做FOXMAIL，那就要用1，2方法了！
