我很头疼，因为PHP mail（）函数不起作用。我已经重新安装了postfix应用程序，但仍然没有变化！ 如果我在端口25中telnet到localhost，我可以从命令行发送邮件
root@server:/etc/postfix# telnet localhost 25

我以前安装过Zpanel，不知道这是不是弄乱了PHP邮件......还有什么可以呢？
我正在使用的PHP mail（）函数非常简单，可以在其他服务器上运行：
mail("testes@hotmail.com","Tell","and","FROM: info@myserver.com.br\n\n");
我得到的错误日志是这样的：

答案 0 :(得分：0)
似乎 hotmail 不喜欢信封发件人www-data@myserver.com.br（在MAIL FROM:中使用）
使用telnet查看hotmail是否已准备好接受来自主机的邮件以及其他信封发件人地址（www-数据可能不受欢迎/阻止）。
如果您使用sendmail程序配置php邮件发送（postfix也提供此类程序），那么您可以设置另一个信封发件人。

所以似乎hotmail阻止了我的消息......我试图向GMAIL发送一些消息，第一个就出来了。 接下来的电子邮件我收到了以下日志

经过一些搜索，我发现问题出在ipv6配置上，所以我编辑了postfix / main.cf和inet_protocols = All到inet_protocols = ipv4。
新输出是这样的
Nov 20 09:54:49 Server postfix/smtp[12315]: 70A3A8AA103: to=<teste@gmail.com>, relay=gmail-smtp-in.l.google.com[173.194.68.27]:25, delay=2, delays=0.21/0/0.4/1.4, dsn=2.0.0, status=sent (250 2.0.0 OK 1384948492 d5si7115120qcj.49 - gsmtp)

但是这位收件人没有收到他的电子邮件，虽然状态良好:(
