imap_open : couldn't open stream to my mail server
Solution 1
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 :
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!
Solution 2
My guess is that you are behind ssl (default port 993)
Try
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
Solution 3
In my case, this did the trick:
imap_open("{mail.domain.com:110/pop3/notls}INBOX", 'login', 'password')
Solution 4
I had the same issue for myself. As you can see.
So, How I solved this:
Go to Your Google Account, You have to change the Security Settings.
Go to Security Tab.
Scroll down and you will find Signing in to Google
Turn OFF
these two settings:
- Use your phone to sign in
- 2-Step Verification
And Turn Less secure app access ON
.
That's all, It worked for me and hope will work for you.

Notice: Unknown: Connection failed to mail.domain.com,143: Connection timed out (errflg=2) in Unknown on line 0
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.
I really don't understand why I can not connect to my mail server
I searched everywhere but I found no answer..

Cannot connect: Array ( [0] => Connection failed to mail.domain.com,143: Connection timed out )

Vivek Muthal about 10 yearsthis error occurs when server doesn't have IMAP Server running. If you are trying to connect gmail or any other mail server then you have to enable imap from settings. And if you have VPS then check you dovecot log.

Max about 10 yearsIf you are using SSL, you likely need port 993. If you're using plaintext, it will be 143. If you're using STARTTLS, it will be 143. Can you telnet from you web host to mail.domain.com 143 and get a * OK prompt?

Max about 10 yearsYour comments above contradict that: you say you have a self-signed certificate, which would only be useful for SSL.
-
PASTAGA about 10 yearsYes I'am sorry. I use SSL protocole but it uses self-signed certificates.

Max about 10 yearsThe default IMAP secure port is 993, not 585.
