This modification is no longer available or supported.

This is a 3.6 specific port of the 3.5 Modification.

In default vBulletin if you send a large number of e-mails, vbulletin either puts them in it's queue and then attempts to send them as each user visits a page, or just simply tries to send them straight away (This is the case when you use the Administrators email users inteface).

As a result of this your server can become seriously overloaded very quickly - so sending several thousand e-mails (like a newsletter) can become very difficult (hours spent clicking 'next' in the ACP) - as a result of these problems, this very simple modification was born.

This modification does two things ;

1. E-mails from the ACP inteface are sent to the mail queue, not straight to the mail system.

2. The processing of the mail queue is set-up as a vb cron item.

Obviously for this to work, you must turn on e-mail queuing in the ACP options - set 'Use Mailqueue System' to 'Yes', and 'Number of Emails to Send Per Batch' to a realistic value (based on the cron setting, as below).

There are two realisitc options for the cron job, you can either set it to run every minute, and set the items to be processed to something small (like 10), or you can do what this modification does by default and set it to run every 10 minutes, and set the items to be processed to something larger (like 100).

Remember, 10 per minute = 600 per hour, 100 per 10 minutes is also 600 per hour. The numbers really depend on how quick you want large queues processed, and how much your mail server can handle in one go.

Once working, when using the ACP mail users inteface, remember you can set it to process 9999 at once (not 500 or whatever) as the mails will now go into the queue, not be sent directly.

Note: This modification will affect any queued e-mails such as subscription e-mails. It will not affect registration e-mails as they bypass queuing anyway.


Upgrading from the 3.5 version.
If you have the 3.5 version installed then you don't need to upgrade - however if you decide to upgrade then you need to delete the current cron job in the Scheduled Tasks Manager and then import the product xml via the ACP Product Manager. The file edits do not need to be changed.


Queue Size

Antivirus has posted a nifty little addon that displays the current size of the mail queue here.

Yes but will I be able to send the email to more than 9999 members? If not this would be useless to forums with more than 10.000 users...

Thanks

I take it you have not used the ACP to email members.

The number is simply the limit to send in one batch (before you have to press a button to move to the next screen, and send the next batch). There is no limit to how many members you can e-mail.

Yes I use it frequently. I understand that it's just to limit the nr in a batch. I thought however that if I use 9999 and this hack it would stop at 9999 and not send an email to the rest of the members...

But after 9999 I would have to click the next button again right? It would be awesome if I could just click once and let it email all members without clicking next.

Well actually, looking at the page you can set the number as high as you want (I just tried it with 999999).

I don't understand what you are asking.

I'm wondering if this would have any effect on the CommBull newsletter add-on (not sure how that one sends emails currently).

Or is only likely to be useful if I use the vBulletin built-in mass emal feature?
