Administrative and Maintenance Tools - Cron Based E-Mail Sending

This modification is no longer available or supported.

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.

This modification includes the code by Antivirus that displays the current size of the mail queue (v3.7.002 onwards).

Version 3.7.003 has the option to add a small delay before each e-mail is sent (between 1 and 9 seconds). Use this option carefully.



History:

v3.7.001 : First Release for vB 3.7
v3.7.002 : Added mail queue size display code.
v3.7.003 : Added option for a delay between the sending of each e-mail.

Hi,

I'm using this mod right now and I must admit it's a life saver ^^ , I wouldn't be able to send out emails without it.

I was wondering though, where do I have to go to see the amount of emails that are left to be sent ?

Thanks

[Paul M]

Thats entirely server/os/control panel dependant (unless you means still to be sent by vb ?).

[losedude]

Yes that's what I mean, how many emails VB has left to send.

[Paul M]

Its displayed in the ACP.

[Paul M]

Unless you have a specific reason then you wont normally need to change it from zero.

Okay I am new to adding plugins and products so this may be a really dumb question so apologies in advance

I have installed this as instructed and already have email queue enabled but where I am stuck is the next step as I do not follow where I change the cron settings:

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).

Any help would be appreciated

Thanks
