错误提示:
不允许使用邮箱名称。 服务器响应为: this mail is blocked by kbas system,blockid=bjapp21.tom.com.15514.1203659604
------解决方案--------------------会不会是他们服务器的问题吗?
------解决方案--------------------没用过tmp.com的.
你确定它的Port是25吗?
另外,你可以试一下sohu的邮箱,是可以用的.我现在就在用,其Port是25
------解决方案--------------------俺测试过,163也不一定能发
不过老版本的可以发送好像是2005以前吧,具体的要看163的文件了
------解决方案--------------------
这是我以前写的,用的是GMAIL的SMTP。我记得YAHOO是没问题的,Tom的不太清楚。你自己试一下。是2.0的。
你的错误会不会是防火墙的问题
