Accounts plugin

[doctor madness]

Hi,

I'd like to use an external IMAP account from roundcube. I enabled accounts (and settings) plugin, I added my server in the list, then I try to create account from "Account administration"
but when I click "Add" button, I get the following error :
"Failed to establish connexion to remote host"

I can connect on port 143 to this host from the server hosting roundcube.
I don't see any error log, what should I do ?

Use this test script to check if you are really able to connect from hosting server:


<?php

function test_connection($username,$password,$imap_host,$imap_port,$prot){ 
                 
     if(function_exists("imap_open")){ 
      if($prot){ 
         $imap_open = "{" . $imap_host . ":" . $imap_port . "/imap/" . $prot . "/novalidate-cert}INBOX"; 
       } 
       else{ 
         $imap_open = "{" . $imap_host . ":" . $imap_port . "/novalidate-cert}INBOX"; 
       } 
      
       if($res = @imap_open($imap_open, $username, $password)){ 
         $success = true; 
         imap_close($res); 
       } 
       else{ 
         $success = false; 
       } 
     } 
     else{ 
       $success = true; 
     } 
        
     return $success; 
    
   }

   // DO NOT EDIT
   if(test_connection("[email protected]","demo","mail4us.net",143,false))
     echo "mail4us.net ok
";
   else
     echo "mail4us.net failed
";

   //EDIT USER AND PASSWORD
   if(test_connection("[email protected]","mygooglepassword","imap.gmail.com",993,"ssl"))
     echo "ssl google ok
";
   else
     echo "ssl google failed
";
?>

Hi,

i just tested :
$php5 test.php

the mail4us.net is ok
the gmail is failed

I added my server like this :
if(test_connection("login","password","my.imap.server",143,false))
     echo "my_own ok
";
   else
     echo "my_own failed
";
and my_own imap server is failed too.
It's an IMAP server. I can connect on it using :
telnet my.imap.server 143
Using thunderbird and other MUA is working too

It's php5 from debian stable.
any idea ?

no one to help me with this little problem ?

Does 'localhost' work for your own IMAP server? Gmail might fail due to missing ssl support of your PHP installation.

[doctor madness]

the test on my locahost is working.
I think it may be related to the remote host. but this hosts is a corporate mail server. where hundreds or thousands people check their mails daily using IMAP (and/or POP)
so I think it should be a bad implementation of IMAP on server side, or php5 imap module

Are you able to connect to gmail by configuring main.inc.php to use ssl://imap.gmail.com:993 ?

[doctor madness]

Hi,

I'm not able to connect to gmail. Maybe I need some php modules, to deal with SSL, no ?

[SKaero]

A lot of hosts block port 993 outbound, I say that's would be the first thing to check.

[doctor madness]

nc -vz imap.gmail.com 993
DNS fwd/rev mismatch: gmail-imap.l.google.com != ew-in-f109.1e100.net
gmail-imap.l.google.com [74.125.77.109] 993 (imaps) open


It seems to be OK. This computer is on a unfiltered network

When to try to connect to gmail using RoundCube what shows up in the error log?

[doctor madness]

Hi,

In my errors log file, I don't have anything regarding problem with Gmail.
I really think the problem with Gmail is due to SSL. Maybe a PEAR module is needed, no ?

My original problem is the access to a non SSL IMAP server. I can connect to mail4us.net using code provided by Rosali. But I can't connect to one of  mine...

Remove "@" sign in front of imap_open command. Perhaps you get some hints by the error message when connection fails.

[doctor madness]

Here are the errors reported when I execute your code without the @ before imap_open :
Warning: imap_open(): Couldn't open stream {imap.gmail.com:993/imap/ssl/novalidate-cert}

[doctor madness]

No idea on this issue ?
