Failed to connect to remote host when trying to save remote IMAP

[hukoeth]

Hi,
I searched the forum but could not find a solution to my problem so I hope someone can hope.
This weekend I switched from a different webmailer to Roundcube and installed the account plugin to connect to different IMAP mailboxes which are all hosted on the same server that also hosts my roundcubce installation.

I have no problem logging in to the IMAP accounts directly but when I try to set up a remote imap account I get the error "Failed to connect to remote host".

I tried using the IMAP_OPEN PHP function to connect to localhost and indeed this fails (although I had a webmailer that uses the PHP IMAP extension).

Does anyone have an idea what else I can try to troubleshoot this?

Thanks,
Uli

Thanks to ren1809 - which gave me remote access to his server - the problem could be tracked down. The imap_open failure is related to self-signed certificates (http://bugs.php.net/bug.php?id=20605). We have to use "/novalidate-cert" flag in the "test_connection" part of the plugin.

But I'm not sure if this is a general solution or if I should make it optional.

Can anyone tell me if I may fix it by simply adding the "novalidate-cert" flag or is it likely that the "novalidat-cert" flag cause problems on other environments? I have tested it on my server an remotely on ren1809's server. Both worked fine.


  function test_connection($username,$password,$imap_host,$imap_port,$prot){
    if(function_exists("imap_open")){
      $rcmail = rcmail::get_instance();
      $password = $rcmail->decrypt($password);
      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;
  }

Hi Rosali,
/novalidate-cert works thank you for the quick answer. However it did not fix the problem that I couldn't switch between the accounts (after selecting an account, I was not able to use the dropdown anymore and the account was not switched).
I managed to get this working by changing line 424 from

Code Select Expand

$rcmail->output->add_footer('<div id=&quot;accounts&quot;>
<a href=&quot;' . $link . '&quot; title=&quot;' . $title .'&quot;>' . $selector . '</a></div>');
to

Code Select Expand

$rcmail->output->add_footer('

' . $selector . '

');
So everything is working now Thanks for this plug-in and your reply.

Cheers,
Uli
