php发送SSL邮件有可能吗？解决了再加分。

[mykelly6]

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。

利用fsockopen连接需ssl认证的站点,和普通的http协议连接确实是有些差异的.
$fp = fsockopen('ssl://www.host.com',443,&$errno,$errstr,30);//类似这样,注意格式以及标准ssl端口号为443

[mykelly6]

fsockopen是php的函数吧，这需要客户租的服务器支持吗？

其实就是网站用户输入的名字，邮箱名和一些信息，客户号称要保护隐私，
非要搞这个，郁闷阿。

这个smtp类也是利用fsockopen进行socket连接的呀.

$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.

没有仔细去看过这个类，呵呵。
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。

[mykelly6]

我现在用的邮箱不支持ssl的，有什么免费邮箱支持这个的吗？
gmail?

[mykelly6]

还有哪位大虾来指点下啊。

[Thaiki]

stream_socket_enable_crypto($fp, true,STREAM_CRYPTO_METHOD_SSLv23_CLIENT);

我也在弄 目前用这个只做到通过 Gmail 的用户密码验证...
