PHP mail（）無法發送郵件| 后綴配置| Apache 2 | Ubuntu 16.04

[英]PHP mail() fails to send mails | Postfix configuration | Apache 2 | Ubuntu 16.04

問題描述

首先，很抱歉，如果這是一篇很長的文章，我想在這里收集所有其他論壇上的人們似乎都認為重要的信息（我記得）。

其次，對於此帖子的答案是否“很明顯”，我深表歉意，但是為了簡單起見，我絕對不知道自己在做什么，這是我第一次嘗試這樣做。

我正在嘗試使用PHP mail（）發送郵件，但是即使每次在學校都可以正常工作，每次都失敗（盡管我在學校和家里都使用PHP7，所以我猜測是這樣）來自我在家中的服務器配置）。

我嘗試過許多教程，要求更新此文件和其他文件，但似乎都沒有對結果產生任何積極影響，所以到目前為止，這是我所做的： 

sudo apt-get install postfix

然后，我在后綴配置過程中選擇了“ Internet站點”和“ localhost”。

我打開了/etc/postfix/main.cf並更改了以下兩個變量的值，這是一些教程和論壇答案所建議的： 

inet_interfaces = loopback-only
inet_protocols = ipv4

如果有幫助，我將同時發布master.cf和main.cf。

我也更改了/ etc / hosts並添加了以下行 

127.0.0.1   localhost localhost.localdomain facorreg

這是完整的/ 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

我在sendmail.mc中添加了以下代碼行（下面是完整的文件）： 

DAEMON_OPTIONS(`Port=smtp,Addr=0.0.0.0, Name=MTA')

最后，我更改了php.ini 

sendmail_path = /usr/sbin/sendmail -t -i

這是/var/log/mail.log告訴我的，當我嘗試向Yahoo地址發送郵件時： 

Nov 17 16:42:13 localhost postfix/pickup[6223]: C5925E20D41: uid=33 from=<www-data>

就是這樣。

以下是一些補充信息，我不知道它們是否有用：

即使我可能是通過嘗試解決問題來弄亂了一些設置，但php mail碰巧在除我自己的工作環境之外的其他任何工作環境中都能正常工作。 通過做一些研究，我發現有些人遇到了與我曾經（現在仍然）相同的問題，他們被告知問題可能來自互聯網提供商（橙色fr）。

我不知道這是否有意義，但就我而言，經驗證據似乎表明了這一點。

我現在將回答這個問題。
