夹缝中求生存
利用php虚拟主机向指定QQ邮箱账户发送一份电子邮件,以163邮箱为例。
前言:在阿里云虚拟主机php的苛刻环境下,php函数库少的可怜,各种不支持,想要发送一份不被收件邮箱屏蔽的邮件,顿时感觉整个世界都黑暗了,不过还好,在夹缝中求生存,踩过了各种坑,最后还是有解决之道的。
- 首先得注册163个人邮箱账号,配置SMTP并设置授权密码(此部分不再赘述,如有疑问请自行百度)。
- 几点提醒:
- 邮件发送成功却未收到邮件提醒:发送的邮件可能被放到了垃圾箱,尤其是注意账户为QQ邮箱的收件人。
- 邮件内容不要太多,否则很有可能会被当成垃圾邮件处理(亲测发送整段html代码邮件会被QQ收件邮箱会屏蔽拒收邮件,而163收件邮箱会正常接收邮件),尤其是注意账户为QQ邮箱的收件人。
- 以下是以163邮箱配置smpt,亲测代码可用,其他邮箱配置smpt未作尝试。
- 已解决自定义发件人,代码中已写明。
- 未解决当收件邮箱为QQ邮箱时,邮件会被QQ邮箱当作垃圾邮件处理的问题。
- 以下是php代码:
test.php
