This appears to be a problem with certain web hosts (GoDaddy, Bluehost ).
Members of the BP community have had success using:
- WP Mail SMTP Plugin ( Recommended )
Ps1 : WP Mail SMTP and Configure SMTP can send a test email which often provides useful debug information.
- Mail From Plugin
- Configure SMTP Plugin
Note :
GoDaddy.com prevents me from sending emails from email accounts other than the ones associated with their hosting service. So try to install "Easy SMTP mail" and configured it with your Godaddy.com email, and it will work.
