Did you change the delivery speed on main newsletter page? Enable the log to info level on diagnostic panel and look at the logs file on wp-content/logs/newsletter: if there is a “limit reached” we can check further few options for your server configuration.
You’re are hitting your server capability. Since the max time is set to 285 seconds, it means you php timeout is the to 300 seconds exactly the maximum run time for a Newsletter batch. Are you using an external SMTP?
Hi, the numbers you’re reporting seem to reveal a max of 1 email per second. Usually this happens when using an external SMTP or when the local SMTP has not a queue configured. Locally you probably have sendmail or postfix or exim: are they configured to send the email directly or as smarthost connecting to an external SMTP?
Ok, I use postfix in my servers as well. You should be able to have better performances since postfix queues mails and then deliver them. Have you setup a cron call to the wp-cron.php page every five minutes?
Ok so i need to setup a wget cron or a php cron to execute wp-cron.php file ?
Another question, the send speed is also influenced by the computing power of the server?
Because now i’ve a 2 core e 2GB of ram.
