Administrative and Maintenance Tools - Cron based e-mail sending

As of 24 Nov 2017 this modification has been withdrawn.

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 does two things ;

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

2. Allows you to add a small delay before each e-mail is sent (between 1 and 9 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 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 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.

How do you delete unsent emails still in the queue? I sent a test email to all my members other than just myself boo

[FRANKTHETANK 2]

and HUH? doesn't answer questions of why i have 12,000 members and its showing 13,624 in my mail queue? when does it ever send all emails?and does it ever stop? how do i check all this? that's why there should be a template or whatever you call it under vb options in ACP

[FRANKTHETANK 2]

JUST KEEPS GOING UP!LOL

There are currently 13,663 unsent emails remaining in the mail queue.

just now

[Paul M]

Maybe you should just remove it and move on.

[obmob]

HAHA, I was thinking that Paul.

Maybe the batch size is too small or the time delay between emails is not 0.

[FRANKTHETANK 2]

cause i want to use this cause i cant do mass email another way. i would like you to tell me how to fix this. you make mod and cant give me support?

[Paul M]

If you want support then maybe saying it sucks is not the way to go
