如何发送邮件?

Question

你的机子上有没有装好smtp服务？如果有的话，需要配置一下php.ini中的
[mail function]
; For Win32 only.
SMTP = localhost; For Win32 only.
;sendmail_from = [email protected]
如果没有 的话找一个不需要验证的smtp服务器填上再不行就想办法申请一个可以smtp的邮箱，然后下载个socket的邮件类来发邮件

Answer 1

可以用fsockopen函数取得$sock资源，然后一步一步fputs函数用命令下来
建议找找相关资料！也可以先找找邮件发送的全过程

Answer 2

我的php.ini里的设置是默认的,也就是
[mail function]
; For Win32 only.
SMTP = localhost; For Win32 only.
;sendmail_from = [email protected]
什么叫做验证的smtp服务器,我资料不要保存,只要页面上的数据通过邮件发送到指定地方就行了,

Answer 3

只是想发信的话，去www.citiz.net 申请一个可以smtp的邮箱
然后用下面贴的类就可以发了<?php

我试试看,不过我的smtp的服务器是公司的一个,也行吧,那也需要验证?
