Administrative and Maintenance Tools - Cron Based E-Mail Sending

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.



History:

v1.12 : First Release for vB 3.6.

"This system" as you call it, is the standard vb mail system. Like I said, the only way to add a delay is to edit the vb mail class.

my server limit us to send just 200 emails per hour. we have about 40000 users and want to send them an newsletter. can I do this with your mod?

regards

[Paul M]

Yes, as long as your send it via the vb mail system.

[asasi]

Is it in admincp ? or need any other mod to install?

Is this updated for 3.6.10pl2? I just sent out a ton of emails and got a lot kicked back saying

  Domain XXX.com has exceeded the max emails per hour (500) allowed.
Message discarded.

Any ideas on this?

It doesnt need updating, as it says ;

Then why would it stop working? Any ideas?

[Paul M]

Because you have changed something. I cannot possible guess what, but nothing just stops working.

How can you purge unsent emails out of the queue? Say you inadvertently send a mass pm and forgot to delete certain usergroups before you sent the pm. How would you purge those before they go out?

Thanks
