Code-Three's email policy states that shared and reseller customers should only sending out a maximum of 500 emails per hour.
This article contains specific instructions on how you can tweak the mailing list program, PHPList, to abide by the code-three.com mailing list policy and send under 500 emails per hour. PHPList is available for automatic install through Fantastico, which is located in your cPanel.
How to throttle PHPList:
- The first step is to locate the configuration file for your phplist installation. If you have installed the script on your domain in a location such as http://www.domain.com/list/, then the physical path will be:
/home/username/public_html/list/config/config.php
In FTP you could see:
/public_html/list/config/config.php - Download this file to your local PC or edit the file with your file manager in cPanel. If you download this file to your PC, you should use a program such as notepad or wordpad.
- Locate the section of code in this file called "batch processing".
- Just below "batch processing", you will see some code as in the following example:
Code:# define the amount of emails you want to send per period. If 0, batch processing
# is disabled
define("MAILQUEUE_BATCH_SIZE",0);
# define the length of one batch processing period, in seconds (3600 is an hour)
define("MAILQUEUE_BATCH_PERIOD",3600);
These are the default settings. We will be replacing those to keep the mails under 500/hour. Here is the code I suggest:
Code:# define the amount of emails you want to send per period. If 0, batch processing
# is disabled
define("MAILQUEUE_BATCH_SIZE",480);
# define the length of one batch processing period, in seconds (3600 is an hour)
define("MAILQUEUE_BATCH_PERIOD",3600);
These settings tell PHPList to send 480 mails per hour. The remaining 20 emails per domain can be used for normal mailing operations if needed. - Save the file and, if downloaded, FTP it back to it's original location. Please, remember to take a backup of the original file just in case you mess up.
Now you should be able to send mails without any bounces and not overloading the mailserver.
