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As of 24 Nov 2017 this modification has been withdrawn.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.

Ok, finally installed... and i have a question, is it ok to set the Use Mailqueue System as "Yes with locking"? o.o

[Paul M]

If you want, that has no bearing on this mod.

[obmob]

Cool, well, i sent my first newsletter, this is a little site, so i set a really low number to test.

I'll search for the logs. Thanks

[obmob]

Hmm... well, i see there is a log as "Process Mail Queue for vBulletin 3.7"

But where cani see the mail queue or any chance to see how many mails were sent on each run? Oo

[bklynjava]

What would the settings look like to send 400 - 450 emails an hour. I was pretty sure I set it right at 75 emails every 10 min.

I tried it and must have done something wrong cause I am currently getting my suspension lifted for sending 1000's of emails.
