原来一直用这个邮件类来发送邮件,忘记是那位大侠写的了,对我这个不懂php的人来说太好用了。
现在有个客户提出要发送SSL邮件,有没有可能把这个改一下支持邮件加密。
具体该怎么做?
如果不行的话是不是可以用租的服务器的form mail功能什么的,如果服务器支持的话。<script language="php">

非要搞这个,郁闷阿。
$mail = new smtp("ssl://mail_host_address",443,true,"user","pass");//注意ssl://和端口443,其它按原来的一样调用,试试看.
做ssl邮件发送应该还需要什么证书,邮件服务器肯定也要支持吧。
没有试着做的环境阿。
