Mail () Failed to connect to mailserver at localhost

Question

Ever since I installed XAMPP with PHP 7, i am unable to send emails from my PHP web applications. The mail() function was doing fine with PHP 5. What could be the issue.
I keep getting "verify your SMTP and smtp_port setting in php.ini" I am not sure what I should do there because it used to work just fine with php5. I am using Windows.
Thanks

I use WAMP and can't send mails too. You will have to install a plug-in (in my case, sendmail) then edit the ini file.
