My PHP does not have the mail function enabled. Which means all mail needs to be funneled through an SMTP Authenticated server.

I find no setting in K2 to do that. Is there a plugin I need? Or is there some way to make K2 use the Joomla Core Mail function?

Hello,

K2 uses the com_mailto component which is a core extension.
We do not use our own mailer.

Then there is something wrong. I can do the mail test in the Global configuration and the test mail goes through. I even get alerts when users sign up. However if you try to use the email link on an article, it does not work. Does this sound like normal behavior? Does the module have issues with SMTP being enable on the core extension?

Hello Frank,
Are you using overrides for this compoment?
Also have you tried looking into Joomla!'s documentation about that particular component?

There are no overrides for the component.
The core component works fine. I can send myself test emails through the core component all day long with no problems at all. The only component that has this problem is K2.

Can you send me a link to your site please?
