Setting Up Email
 

I am on 3.8.3 and having problems with the registration emails going through. I have checked trhe email settings and when I do a diagnostics, I get the following error:

Quote:
The mailing function returned an error while trying to send the mail. Check your mail server to ensure it is configured correctly to allow PHP to send mail from it. You should also check your mail server's error log for more diagnostic information.
Where should I go to look for these settings?

Thanks so much-
John
