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
Just below "batch processing", you will see some code as in the following example:
Code:These are the default settings. We will be replacing those to keep the mails under 500/hour.
Here is the code I suggest:
Code:These settings allows PHPList to throttle 450 mails per hour, exactly as our TOS suggests. The remaining 50 emails per domain remain available for normal mailing operations.
Now you should be able to send mails without any bounces and not overloading the mailserver.
