Administrative and Maintenance Tools - Cron based e-mail sending

--------------------------------------------------------------------------------
This modification has been withdrawn.
vBulletin 4.0.x and 4.1.x are no longer supported.

The feature is already built into the core vBulletin 4.2.x code.
--------------------------------------------------------------------------------


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

The result of this can be that your server can gets seriously overloaded very quickly - or on many hosts, you get banned for exceeding their e-mail sending limits. This can make sending several thousand e-mails (like a newsletter) very difficult.

This modification helps in three ways ;

1. The processing of the mail queue is set-up as a vbulletin cron item.

2. You can add a small delay before each e-mail is sent (0,1,2 or 5 seconds).

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

Use option 2 carefully, otherwise you will slow your e-mail system right down.

For this to work, you must use e-mail queuing (ACP Options - Use Mailqueue System = Yes) and also the 'Number of Emails to Send Per Batch' needs to be a realistic value (see below). The installation process will attempt to set these options for you. This modification also requires two file edits to work correctly.

There are two 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 80, which is the default).

Remember, 10 e-mails per minute = 600 per hour while 80 e-mails every 10 minutes is 480 per hour. The numbers you set really depend on how quick you want large queues processed, and how much your mail server can handle in one go. The default settings are fine for most people.

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

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

This modification also displays the size of the e-mail queue in the ACP homepage, based on code supplied by Antivirus.

To install, download and uzip the files, then follow the instructions in the text file.

Hi Paul

I tried using this in conjunction with a mod of mine which sends to all users of a specific social group a notification when a new thread is made in a specific forum. This can be well about 4500 e-mails. But when I try to submit a new thread, it gets inserted into the database but the page keeps hanging until it times out. Is it taking so long for the e-mails to be inserted into the queue? Because even after waiting for a while, no e-mails show up in the e-mail queue.

You can find the code I am using here: https://vborg.vbsupport.ru/showthrea...19#post2334619

Thank you very much

For me this one is better than the one integrated in vb 4.2.0.. With the integrated tool, i have always the queue full. Unuseful tool. I'll reinstall this one on my 4.2.0.

--------------Edit--------------

Not compatible with 4.2.0. Paul please help me.

Does It work without manually file edit on 4.1.10 ?

[carrlos]

I was using this mod until updating to 4.2.0 last week. I have not received a new registration email since then. I'm not sure if it's related or not but I don't even know where to begin troubleshooting. Users are getting the activation email but I stopped getting emails of new registrations or emails from forums where I asked to be notified of new posts and threads. Can anyone point me in the right direction to begin troubleshooting?
