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As of 24 Nov 2017 this modification has been withdrawn.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

You cannot, unless you use something like phpadmin to actually delete the records from the email queue table.

can i use this on my vb 3.7.1?

I'm asking as it's written in 3.7.x version that it's not supported.

[Paul M]

Installing a 3.8 version on 3.7 would not be supported either.

PROBLEM

Hi, I've come across a problem. I have this installed but when I check my schedule logs, the cron does not appear to have been run. Its set to run every 10 minutes.

Even when I click "run now" from the schedule task manager menu in admincp, it goes to this screen "Process Mail Queue for vBulletin 3.7" but gets stuck there.

Any advice please?

My email unesent queue is growing as none are been sent. Any help or advice would be greatly appreciated thanks Mally

It isnt supported because I only support the 3.8 versions of my mods (as I only run 3.8).

There are no known issues with the 3.7 version.

If you dont get an error message then there isnt much i can tell you - it sounds like your server is unable to send mail. Have you tried this in the diagnostics ?

JFYI, Im about to go on holiday, so I may not actually see your reply until the end of next week.
