Connecting to Gmail through IMAP with PHP - SSL context failed

One more additional thing you need enabled in PHP, is the OpenSSL extension. It appears that the IMAP Client library (with SSL) depends on this.

It doesn't matter if Apache has the OpenSSL module enabled as this is processed/handled before the request is handed off to PHP.

The following discussion thread may help shed some light:

had the same problem with personal domain on google apps. Problem was solved by changing application access to account. Simply follow by link and turn ON access to account.

This has worked for me after a long effort:

$ServerName = "{imap.gmail.com:993/imap/ssl/novalidate-cert/norsh}Inbox";

I was facing same problem. I am using windows and wamp and my wamp "openSSl" extension is enabled.

I removed this issue by using following steps.I hope this will work for you too.

1) Logged in via browser to gmail account.

2) Open this url "https://www.google.com/settings/security/lesssecureapps"

3) Click at "turn on"

4) try following code

<?php

set_time_limit(4000);


// Connect to gmail
//$imapPath = '{imap.gmail.com:993/imap/ssl}INBOX';
$imapPath = '{imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX';
$username = '[email protected]';
$password = 'Your-password';

// try to connect
$inbox = imap_open($imapPath,$username,$password) or die('Cannot connect to Gmail: ' . imap_last_error());

         $output .= imap_body($inbox, $mail, FT_PEEK);
    } else {
        //    
    }
   echo $output;
   $output = '';
}

// colse the connection
imap_expunge($inbox);
imap_close($inbox);


?>
