首先,对不起,如果这是一个很长的帖子,我正在尝试收集所有信息(我记得),其他论坛上的人似乎发现重要.
其次,如果这篇文章的答案恰好是“明显的”,我很抱歉,但为了简单起见我绝对不知道我在做什么,这是我第一次尝试这样做.
我正在尝试发送带有PHP邮件的邮件(),但是每次我在家里都这样做就会失败,即使它在我的学校工作得很好(我在学校和家里使用PHP7,所以我猜它来自我家的服务器配置).
我已经尝试了很多教程要求更新这个文件和其他文件,其中没有一个似乎对结果产生任何积极的影响,所以这就是我到目前为止所做的：
sudo apt-get install postfix
然后我在postfix配置期间选择了“internet site”和“localhost”.
我打开/etc/postfix/main.cf并更改了以下两个变量的值,因为一些教程和论坛答案建议：
inet_interfaces = loopback-only
inet_protocols = ipv4
如果有任何帮助,我会发布master.cf和main.cf.
我改变了/ etc / hosts并添加了以下行
127.0.0.1 localhost localhost.localdomain facorreg
这是完整的/ etc / hosts
127.0.0.1 localhost
127.0.1.1 facorreg
127.0.0.1 localhost localhost.localdomain facorreg
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
我将以下行添加到sendmail.mc(我将通过以下完整文件)：
DAEMON_OPTIONS(`Port=smtp,Addr=0.0.0.0, Name=MTA')
最后,我改变了php.ini
sendmail_path = /usr/sbin/sendmail -t -i
当我尝试将邮件发送到雅虎地址时,这是/var/log/mail.log告诉我的内容：
Nov 17 16:42:13 localhost postfix/pickup[6223]: C5925E20D41: uid=33 from=<www-data>

这就是它.

在此先感谢您的帮助.
最佳答案 虽然我可能通过尝试解决我的问题搞砸了一些设置,但是除了我所在的地方之外,php邮件恰好在任何其他工作环境中正常工作.通过一些研究,我发现有些人遇到了我曾经(并且仍然有)的相同问题,他们被告知这些问题可能来自互联网提供商(Orange fr).
我不知道它是否有意义,但就我而言,经验证据似乎指明了这一点.
我现在将这个问题作为回答.
