See this: https://xenforo.com/community/resources/email-troubleshooting-guide.5086/

But generally, you would need to contact your host. It sounds like their mail sender (the MTA) has stopped.

thanks mike ! so i need just use other email at default?

 

[sandokloud]

for a moment I thought I was attacked by hackers hehe

 

[Mike]

If you haven't resolved this, you'd either need to contact your host or change XenForo's email settings to use an external SMTP server.

 

[sandokloud]

I was already using an external e-mail, if I were to use the email exenforo what would be?specifically which settings should I change? as in the design of the links that you have previously shown?

 

[Mike]

That specific error only occurs if you're using the default PHP mail option, not an external SMTP server. If you don't remember changing the settings in XenForo, it's worth double checking the email setting specifically to confirm it's what you expect.

fix was just a smtp email not working
