嗨，我正在研究一些代码，以将Gmail中的某些帐户映射到LAMP服务器，我以前已经做过，现在尝试使用相同的代码，但是毫无用处，好了，我整天都在这里阅读很多内容，这就是我已经做到现在为止。
我在gmail上启用了imap转发。从这里https://support.google.com/mail/answer/7126229?hl=en&authuser=7&visit_id=637046170242826287-1928730887&rd=2
我已允许访问Google帐户中不安全的应用程序
我已设置两步验证：打开+创建了应用密码
最后两个方法都是同一回事。
好吧，我尝试这样的连接：
curl -v --insecure --url "imaps://imap.gmail.com:993" --user "myuser4@gmail.com:mypassword"
并获得
* About to connect() to imap.gmail.com port 993 (#0)
* Trying 2607:f8b0:400c:c0d::6d...
* Connected to imap.gmail.com (2607:f8b0:400c:c0d::6d) port 993 (#0)

< C OK hmyuser@gmail.com authenticated (Success)
Etc................................................................
然后一切正常，因为我是从VM上的服务器上运行网络的，所以一切正常。
然后
$ php -v

已安装软件包 php-imap
<?php
$hostname = '{imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX';
$username = 'myuser@gmail.com';
$password = 'mypassword';
$mbx = imap_open($hostname,$username,$password)or die('Cannot connect: ' . print_r(imap_errors($mbx)));
?>
这很奇怪
Warning: imap_open(): Couldn't open stream {imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX in /var/www/html/imap/connect.php on line 8
Notice: Unknown: Can't connect to gmail-imap.l.google.com,993: Permission denied (errflg=1) in Unknown on line 0
Notice: Unknown: Can't connect to gmail-imap.l.google.com,993: Permission denied (errflg=1) in Unknown on line 0
Notice: Unknown: Can't connect to gmail-imap.l.google.com,993: Permission denied (errflg=2) in Unknown on line 0
但如果我这样做
if (function_exists('imap_open')) {
echo "IMAP functions are available.<br />\n";
} else {
echo "IMAP functions are not available.<br />\n";
}
它提供了IMAP功能。

我正在考虑，发现应该是SELinux，然后
`$ setenforce 0`
和
` $ getenforce
Permissive`
，然后重试一次，但是我不想禁用SELinux
然后我找到
setsebool -P httpd_can_network_connect 1
