[imp] Re: IMP connects twice to POP server

[Carlton Thomas]

Chuck,

Thanks for your response. However, my comments re: the number of
accesses to the server was just a passing comment and I was not
looking for an answer to that question.

My main question was related to the almost simultaneous access to
the POP server which will cause IMP to fail to authenticate. I have
looked at the PHP code and suggest that some re-try logic be added
to attempt the connection again in the event of a failure. I have
done this myself and have eliminated the problem i was experiencing.

What I did was to replace the the statements which connect to the
server in "imp/lib/IMP.php" with the following:-

        /**
        * If the imap_open fails, this may be due to a transient error, so just
        *  retry the operation. If it still fails after the attempts then give up
        */
        $timer = 0;
        $imp['stream'] = false;
        while ($timer < 5 && !$imp['stream']) {
            if ($flags == 0) {
                $imp['stream'] = @imap_open($connstr, $imp['user'], Secret::read(Secret::getKey('imp'), $imp['pass']));
            } else {    
                $imp['stream'] = @imap_open($connstr, $imp['user'], Secret::read(Secret::getKey('imp'), $imp['pass']), $flags);    
            }    
            if (!$imp['stream']) {
                sleep (1);
            }
        }


I am not sure what the max value of the loop counter should be,
however, five seems OK for the tests I did. Will this fragment
of code help others who may be experiencing the same or similar
problems?

Now that I got it working, there are a number of other little
problems, but I will create new threads for those.

Thanks again for your reply and thanks for your efforts in
creating this great product.

Regards !

Subject: Re: [imp] Login form on non-imp page...

I can't seem to login and it redirects to imp/login.php with the following error

login.php?1=1&imapuser=myusername&server=imap&reason=failed


is there any other files i have to change besides the to change besides 
customize_login.php    ?

----------------------------

// CUSTOMIZE THIS
define('IMP_BASE', '..');

require_once IMP_BASE . '/lib/base.php';
require_once IMP_BASE . '/config/servers.php';

/* Set up the password encryption token. */
Secret::setKey('imp');

/* Use the first server defined in servers.php. */
// CUSTOMIZE THIS
$server = key($servers);

?>

<!-- CUSTOMIZE THIS -->
<form action="<?= Horde::applicationUrl('redirect.php') ?>" method="post">
User: <input name="imapuser" tabindex="1" type="text" size="20" /><br />
Pass: <input name="pass" tabindex="2" type="password" size="20" /><br />
<input type="hidden" name="server" value="<?= $server ?>" />
<input type="submit" value="Log in" />
</form>
