imap_open : couldn't open stream to my mail server
提问by TOZ
Notice: Unknown: Connection failed to mail.domain.com,143: Connection timed out (errflg=2) in Unknown on line 0
注意：未知：连接到 mail.domain.com 失败，143：连接超时（errflg=2）在第 0 行的未知中
imap_open("{mail.domain.com:143/novalidate-cert}INBOX", 'login', 'password')
The port 143 is open, I'm not behind a firewall, my server uses self-signed certificates.
端口 143 已打开，我不在防火墙后面，我的服务器使用自签名证书。
I really don't understand why I can not connect to my mail server
我真的不明白为什么我无法连接到我的邮件服务器
I searched everywhere but I found no answer..

Thank you for your answers. My mistake was not coming from the connection but rather a loop that crashed the server when I had too much email :
谢谢您的回答。我的错误不是来自连接，而是当我有太多电子邮件时导致服务器崩溃的循环：
imap_open("{mail.domain.com:143/novalidate-cert}INBOX", 'login', 'password')
$mails = imap_search($stream, 'UNSEEN');
rsort($mails);
foreach ($mails as $mailId) {
imap_fetch_overview($stream, $mailId, 0);
} //that was the mistake when email number is too big!

In my case, this did the trick:
就我而言，这解决了问题：
imap_open("{mail.domain.com:110/pop3/notls}INBOX", 'login', 'password')

My guess is that you are behind ssl (default port 993)
我的猜测是你在 ssl 后面（默认端口 993）
Try
尝试
imap_open("{mail.domain.com:993/imap/ssl/novalidate-cert}INBOX", 'login', 'password') or die('Cannot connect: ' . print_r(imap_errors(), true))
Dont forget to open that port
不要忘记打开那个端口

I have written a library.
Don't know it will work for your host or not.
But you could surely try it. http://vivoauthimap.vivsoftware.in/
我写了一个库。
不知道它是否适用于您的主机。
但你肯定可以试试。http://vivoauthimap.vivsoftware.in/

In my case, the imap extension was compiled without the --with-imap-ssloption. You need to pass it to configureor if you're using Docker:
就我而言，imap 扩展是在没有--with-imap-ssl选项的情况下编译的。您需要将它传递给configure或者如果您正在使用 Docker：
docker-php-ext-configure imap --with-imap-ssl
docker-php-ext-install imap
You can verify if there is an SSL Support using this command:
您可以使用以下命令验证是否有 SSL 支持：
php -i | grep imap -A 5
If there is no "SSL Support => enabled" string, you need to recompile the imap extension.
如果没有“SSL Support => enabled”字符串，则需要重新编译 imap 扩展。
Lack of SSL Support was resulting in not very clear error messages:
缺乏 SSL 支持导致错误消息不是很清楚：
Warning: imap_open(): Couldn't open stream {imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX
Can't open mailbox {imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX: invalid remote specification
