稳定经得住考验的smtp发送邮件的类(请付上使用方法),万分感谢

求一个稳定经得住考验的smtp发送邮件的类(请付上使用方法),万分感谢!我找了几个,有的不能用,发不出,有的居然没有正文;还有一个正文这些都有,但没发几封就说 "帐号已经被锁定 ",discuz\phpwind这些的邮件类又搞得太复杂,剥离不出来!谢谢拉!!!用mail函数和iis得smtp,它又老是说address   invalid!怎么改地址都不行: "aaa "   or   "[email protected] ",都是错得如果比较大,[email protected],请发到邮箱,谢谢!发邮件者20分起哈,如果正确得话60分起!------解决方案--------------------php
