Major Features:

Bounced Mail Handling: Once configured, it will (if so desired) automatically track and handle bounced mail. Alternatively, you can manually handle bounced mail if you so wish.

Automatic "Unsubscribe" Link Creation: If the user receiving the mail has access to unsubscribing, a secure link to unsubscribe themselves from the mailing list will be automatically added to the bottom of the mail. It does not require the user to be logged in, so it complies with spam policies set forth by mail providers.

Mail History: Each past sent mail can be viewed at any time from the front-end.

Advanced Subscription Management: Users can quickly and easily (un)subscribe from the mailing list via the mailing list directory, or the admin can manually change the subscription status in the AdminCP.

Bounced Mail Threshold: When an admin-configured number of mails bounce from the same email address, the user is automatically removed from mailing lists and all other email-related vBulletin features, and notified via PM what happened to their account, as well as directions to change their email addresses.

Firstly thanks for the great hack. It is well written, has a clean code and from checking the source code, I can confirm that a lot of work is put into the project so frankly speaking I believe it is not appreciated enough. So I wanted to tell my appreciation for your work first! :-)

I installed it in a friend's board. He wants to use for bounce email management and not interested in email listing features so my comments are regarding this part only. During installation I had some issues, glitches and fixes for them so I wanted to share with you considering you might want to know about them.

ISSUE 1:

During the initial installation the hack didn't work first. It gave no signal but it was not processing any bounced emails. After some debugging, I noticed that imap_open() was failing with error:
Warning: imap_open() [function.imap-open]: Couldn't open stream {mail.___.com:143/imap}Inbox in [path]/dbtech/vbmail/includes/class_imap.php on line 98
Although all login details were correct.

After some work I noticed our server is requiring /novalidate-cert parameter otherwise, it is dieing with error:
Certificate failure for
___.com: self signed certificate:
/C=US/ST=Unknown/L=Unknown/O=Unknown/OU=Unknown/CN=server1.____/emailAddress=ssl@server1.___"

So changing the line in dbtech/vbmail/includes/class_imap.php:

PHP Code:


			
self::$connection = imap_open(
                '{' . self::$vbulletin->options['dbtech_vbmail_imap_host'] . ':' . self::$vbulletin->options['dbtech_vbmail_imap_port'] . '/imap' . 
                    (self::$vbulletin->options['dbtech_vbmail_imap_ssl'] ? '/ssl/novalidate-cert' : '') . 
                    (self::$vbulletin->options['dbtech_vbmail_imap_tls'] ? '/tls/novalidate-cert' : '') . 
                '}' . self::$vbulletin->options['dbtech_vbmail_imap_mailbox'],
                self::$vbulletin->options['dbtech_vbmail_imap_username'],
                self::$vbulletin->options['dbtech_vbmail_imap_password']
            );

as

PHP Code:


			
            //Logician Hack : Added /novalidate-cert as mail server is rejecting connection without this
            self::$connection = imap_open(
                '{' . self::$vbulletin->options['dbtech_vbmail_imap_host'] . ':' . self::$vbulletin->options['dbtech_vbmail_imap_port'] . '/novalidate-cert/imap' . 
                    (self::$vbulletin->options['dbtech_vbmail_imap_ssl'] ? '/ssl/novalidate-cert' : '') . 
                    (self::$vbulletin->options['dbtech_vbmail_imap_tls'] ? '/tls/novalidate-cert' : '') . 
                '}' . self::$vbulletin->options['dbtech_vbmail_imap_mailbox'],
                self::$vbulletin->options['dbtech_vbmail_imap_username'],
                self::$vbulletin->options['dbtech_vbmail_imap_password']
            );
            //Logician Hack : Added /novalidate-cert as mail server is rejecting connection without this

fixed this issue for us.

I think it might be a good idea to:
1- Add a hack setting to enter custom parameters there. Alternatively you can make "IMAP Port" setting inputbox "string", instead of "number" which will then allow entering values like: 143/novalidate-cert
2- In part:

PHP Code:


			
if (!self::$connection)
            {
                // We couldn't open the mailbox
                trigger_error($vbphrase['dbtech_vbmail_cannot_open_mailbox'], E_USER_ERROR);
            }

It might be helpful to vbmail() admin with the value of imap_last_error() variable as it will help debugging connection problems when hack can't connect to the mail server. ATM admin is in dark when a connection problem occurs as no error etc. are returned. (Even when scheduled task is run manually in admin cp)

ISSUE 2:

In dbtech /vbmail/cron/threshold.php, this part:

PHP Code:


			
$users = $vbulletin->db->query_read_slave("
    SELECT
        user.userid,
        user.username,
        user.usergroupid,
        user.membergroupids,
        user.infractiongroupid,
        user.displaygroupid" . ($vbulletin->products['dbtech_vbshop'] ? ", user.dbtech_vbshop_purchase" : '') . "
    FROM `" . TABLE_PREFIX . "dbtech_vbmail_message` AS dbtech_vbmail_message
    INNER JOIN " . TABLE_PREFIX . "user AS user ON(user.email = dbtech_vbmail_message.fromaddress)
    WHERE dbtech_vbmail_message.fromaddress != ''
        AND dbtech_vbmail_message.bounce = '1'
        AND user.dbtech_vbmail_bounceflag = '0'
    GROUP BY dbtech_vbmail_message.fromaddress
    HAVING COUNT(*) >= " . intval($vbulletin->options['dbtech_vbmail_bounce_threshold'])
);

Should be replaced as:

PHP Code:


			
$users = $vbulletin->db->query_read_slave("
    SELECT
        user.userid,
        user.username,
        user.email,
        user.usergroupid,
        user.membergroupids,
        user.infractiongroupid,
        user.displaygroupid" . ($vbulletin->products['dbtech_vbshop'] ? ", user.dbtech_vbshop_purchase" : '') . "
    FROM `" . TABLE_PREFIX . "dbtech_vbmail_message` AS dbtech_vbmail_message
    INNER JOIN " . TABLE_PREFIX . "user AS user ON(user.email = dbtech_vbmail_message.fromaddress)
    WHERE dbtech_vbmail_message.fromaddress != ''
        AND dbtech_vbmail_message.bounce = '1'
        AND user.dbtech_vbmail_bounceflag = '0'
    GROUP BY dbtech_vbmail_message.fromaddress
    HAVING COUNT(*) >= " . intval($vbulletin->options['dbtech_vbmail_bounce_threshold'])
);

Otherwise email part in the user pm is blank.

ISSUE 3:

The hack is not unflagging user if vb option "verifyemail" is turned off since you tied unflagging only to register.php user activation screen. I added this pluggin to correct this issue for boards which does not use email confirmation:

HOOK LOCATION: profile_updatepassword_complete
PHP CODE:

Quote:

//Logician Hack : If user is not banned AND changed his email correctly AND email verification is OFF, THEN unflag dbtech_vbmail_bounceflag setting
if ($permissions['genericoptions'] & $vbulletin->bf_ugp_genericoptions['isnotbannedgroup'] AND ($vbulletin->GPC['email'] != $vbulletin->userinfo['email'] AND $vbulletin->GPC['email'] AND $vbulletin->GPC['emailconfirm'] == $vbulletin->GPC['email']) AND !$vbulletin->options['verifyemail'])
{

$onoff = '0';
$userdata->set('dbtech_vbmail_bounceflag', $onoff);
}

This fixed the issue for such boards.

If I run into other issues, I'll keep reporting.

And once again, thanks for the great hack and efforts put into it!

Thank you! You're actually the first person (outside the DBTech team

) that's complimented me on my code quality, so it really means a lot

I presume there's no downside to adding novalidate-cert for everyone? Surely no servers can be set up to hard reject a connection that tries to skip certificate validation as opposed to simply ignoring that directive... Thinking out loud here. I'd prefer to have it working without requiring admins to edit the port like that

I've added the novalidate-cert and the imap_last_error() to the file and it'll be updated with the next version

Whoops xD

And this is the kicker that requires a new version number as opposed to a hotfix xD

I'll release it later tonight alongside a vBActivity & Awards update, thanks

I've been reported that sometimes this error shows up for admin:

PHP Code:


			
Fatal error:  Class 'VBMAIL' not found in /home/..../public_html/forum/dbtech/vbmail/hooks/mail_send.php on line 10

I traced it a little and noticed it could only happen during vb cron mailing. You include the class in "global_bootstrap_init_complete" hook so it should be there in all page visits but there must be a vb section which triggers vb mail cron for admin visitor without initializing "global_bootstrap_init_complete" hook to produce this error. I'm still working on it to find where but wanted to report here in case you also have an idea.

DragonByte Tech · #**106** 11-14-2011, 02:17 PM

My guess is that the Cron doesn't use vB's bootstrap to initialise. Since cron mailing don't need vBMail stuff anyway, I'll edit the mail_send hook with this

PHP Code:


			
    if (class_exists('VBMAIL') AND VBMAIL::$pluginglobals['mailinglist'])

That should work

Why doesn't cron mailing need vbmail stuff? Daily/weekly digest, birthday greetings, event reminder are performed via cron. Actually so is ALL mailing process if "Use Mailqueue System" setting is turned on in vb. Am I missing something?

DragonByte Tech · #**108** 11-14-2011, 02:54 PM

Because bounced mail collection is not strictly dependent on anything in that hook, the headers simply help it identify the source

Not to mention anything within that if condition I posted is only supposed to happen on vBMail's own pages anyway

Yes collecting is not needing that hook but I assumed email sending depended on that since it needs to check if bounce flag is for the TO: user on. But I guess I'm safe to assume this class is not needed during that process, right?

DragonByte Tech · #**110** 11-14-2011, 03:33 PM

Correct

Fillip

Logician · #**111** 11-14-2011, 05:56 PM

ok thanks!

And one more issue I pulled from PHP error log: When threshold.php runs on cron, it is producing "PHP Fatal error: Call to undefined function print_cp_message() in /home/.../public_html/forum/includes/class_dm.php on line 1092"

When I run the cron in scheduled tasks, it does not produce the error so I believe it only happens when it runs on its own.
