Ubuntu中启用php的mail()函数并解决发送邮件速度慢问题
本文主要给大家介绍的是在Ubuntu下安装sendmail的方法,以及启用sendmail之后,php发送邮件缓慢的原因及解决方法,有需要的小伙伴可以参考下。
如果需要用php的mail()函数来发送邮件,是需要服务器安装sendmail组件才能支持的,这个在php的手册中mail()函数部分也有介绍到。然后在
在Ubuntu下安装sendmail的命令:
代码如下:
sudo apt-get install sendmail
安装好之后,启动sendmail服务:
代码如下:
sudo service sendmail start
有了sendmail的支持,就可以在php中用mail()函数发送邮件了。
一般造成在php用mail()发送邮件缓慢的原因,是DNS解析慢导致,又常常是因为服务器的hostname不是一个真实可解析的域名。
代码如下:
sudo vim /etc/hosts
然后按i键,然后就可以修改代码了。在127.0.0.1那段里面添加localhost.localdomain和你的主机别名,改好之后按Esc键退出编辑状态,然后输入‘:wq'保存并退出。
最后重启下sendmail服务:
代码如下:
sudo service sendmail restart
