Solved Changing from phpmailer to Joomla default

Hi there,

I run a website with quite a bit of traffic (over 200 subscriptions per forum category) and we are running into some issues with the following things. My assumption is as following. Kunena does not use the standard email settings from Joomla but uses a phpmailer that runs via the hosting server. This leads to the following challenges. 

Current site:
- Setup to run joomla emails via a paid gsuite subscription (SMTP connection)
- Hosting via a local party with a phpmailer protection against spam

1. The emails sent are not verified via DKIM/SPF due to our current setup, what can do I? Other then adding the SPF for the hosting provider
2. We reach out limit on sending emails via the hosting provider, is there any way we can NOT use the phpmailer but switch to a different authentication method?

Much appreciated!

Depending on the Joomla settings, mails are sent either via SMTP as well as PHP mailer. The sending can be limited in the Kunena configuration (at Subscriptions).
Quote from the backend:
"If value > 1, send a single subscription e-mail to multiple recipients. Using relatively large value prevents your site from sending too many e-mails if your web host limits the amount of e-mails per second or per hour. Larger value also improves performance as less e-mails needs to be sent."

Hi Rich,
The option was already set to a 100. Our webhoster does put us in the spam and stops our emails from being sent. Somehow it is not using the Joomla default email settings (SMTP). Can you help me out please?

Hello,

Kunena uses the Joomla! settings to send the emails, some mail provider like Microsoft 365 can blocks the mailbox when if you sent more than a number of mails in the same time

Is there a way to check it? Our hosting provider states were using a phpmailer script however it's all set up to use a smtp service outside of our provider

The send() method from MailTemplate class from Joomla! which is used by Kunena github.com/joomla/joomla-cms/blob/4.2-de...ailTemplate.php#L187 , send at the end the mail by by PhpMailer class. Then PhpMailer send to SMTP service defined in Joomla! configuration
