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This modification has been withdrawn.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.

For some reason it doesn't send out the mails.

They stay in the E-Mail Queue.

Can anyone confirm that this mod does work with 4.0.3?

[Paul M]

Yes. It works on 4.0.3, and any other 4.0.x version.

[dtommy79]

Strange, because it puts the emails in the Queue but it doesn't send them.

It works if I run the task manually.

[Paul M]

Then you have an issue with your cron jobs running.

[hayatt2000]

Thanks

[Kaosvf]

or you can do what this modification does by default and set it to run every 10 minutes

How can I do it?

[Alecsmith]

Thanks installed

This doe snot seem to work in 4.0.7. I turned off the task to Process the Email Queue, and emails are being sent out in less than 1 minute.

It seems like 4.0.7 is ignoring this product.

[Paul M]

Some e-mails (like registration e-mails) are never queued.

However, the more likely answer is you didnt re-do the file edits after you upgraded to 4.0.7.
