imap_open : couldn't open stream to my mail server

imap_open(): couldn't open stream gmail
php imap
imap_open couldn t open stream outlook office365 com 993/imap ssl/novalidate-cert inbox
php imap open folder
php pop3
imap_search
cannot connect to gmail: too many login failures
php monitor email inbox

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..

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!

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

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/

In my case, the imap extension was compiled without the --with-imap-ssl option. You need to pass it to configure or if you're using 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:

php -i | grep imap -A 5

If there is no "SSL Support => enabled" string, you need to recompile the imap extension.

Lack of SSL Support was resulting in not very clear error messages:

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

The old "Warning: imap_open(): Couldn't open stream" message , Have gotten a bit further with enewsletter since I first reported my imap_open() issues here; http://drupal.org/node/41143#comment-75745. Tutorials, PHP & MySQL, IMAP This first tutorial will show you how to use imap_open to connect to a imap mail server. To connect to an IMAP server using imap_open requires 3 parameters the host = either an ip address of the domain name, username = the email address and mailbox login name and finally the account password.

  • what error are you getting?
  • Cannot connect: Array ( [0] => Connection failed to mail.domain.com,143: Connection timed out )
  • this 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.
  • If 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?
  • Same problem when i try to download too big email it is showing.... imap_open(): Couldn't open stream {imap.gmail.com:123/imap/ssl}INBOX in,,,,,,,,,,,,,Cannot connect to Gmail: Can not authenticate to IMAP server: [ALERT] Please log in via your web browser: support.google.com/mail/acco..........what mistake am i doing please let me know
  • Your comments above contradict that: you say you have a self-signed certificate, which would only be useful for SSL.
  • Yes I'am sorry. I use SSL protocole but it uses self-signed certificates.
  • The default IMAP secure port is 993, not 585.
