change to
change smtp_port to smtp_port=587
change smtp_ssl=auto to smtp_ssl=tls

uncomment ;error_logfile=error.log to error_logfile=error.log
uncomment ;debug_logfile=debug.log to debug_logfile=debug.log
write your gmail id in auth_username: auth_username=*****
write your gmail password in auth_password: auth_password=*****

change hostname to hostname=localhost


Go to C:\xampp\php: open php.ini file in notepad or any text editor goto [mail function] part and make the changes as follows.

comment SMTP=localhost by putting semicolon infront=>;SMTP=localhost
comment smtp_port=25 by putting semicolon infront=>;smtp_port=25
comment sendmail_from= by putting semicolon infront=>;sendmail_from=specify path of
 file in sendmail_path to sendmail_path=C:\xampp\sendmail\sendmail.exe

check if extension=php_openssl.dll is enabled=>If there is semicolon in front then
 un-comment it by removing that semicolon


After following the given steps if the mail is not sent by calling the mail function, then goto C:\xampp\sendmail open error.log to see the error occurred.
