The below is the response from the hosting provided -
"By default, the mail() function is enabled on our hosting servers using PHP.
If you use the mail() function in your PHP, you do not need to specify an outgoing mail server. If you are using some other method besides mail() in your PHP code, use relay-hosting.secureserver.net for your relay server."
The PHP mail function is not working due to some reason, I have tried few of the plugins (Cimy Swift, Configure SMTP, WP-Mail-SMTP) but none of them worked.
Kindly let me know where I can change the scripts to include the relay server details (I have the access to all the files to edit).
Thanks.
