问题描述
我正在使用gmail作为phpmailer()的smtp服务器.
I'm using gmail as my smtp server with phpmailer().
$mail->Host= "ssl://smtp.gmail.com"
在与gmail的连接失败的情况下,如何作为备份来指定单独的smtp服务器?
How do i specify a separate smtp server just as a back up incase the connection to gmail fails ?
推荐答案
PHPMailer内置了不需要繁琐的工作.设置主机时,只需在以分号分隔的列表中添加多个主机(也可以同时指定安全设置),如下所示:
No need for all that hard work, it's built in to PHPMailer. When you set the host, just add more than one in a semicolon-delimited list (you can also specify security settings at the same time), like this:
$mail->Host = 'tls://smtp.gmail.com:587;tls://smtp2.gmail.com;ssl://mail.example.net:465';
在放弃之前,PHPMailer将按照提供的顺序尝试全部操作.确保您使用的是最新版本的PHPMailer,因为较早版本的该区域中存在错误.
PHPMailer will try them all, in the provided order, before giving up. Make sure you are using a fairly recent version of PHPMailer as there were bugs in this area in older versions.
