Hi saiful! I think you need config in xampp. You can follow the steps:

• Open php.ini file in C:\xampp\php\php.ini find extension=php_openssl.dll and **remove **the semicolon from the beginning of that line to make SSL working for gmail for localhost.
• Continute find [mail function] and change:

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "\"C:\xampp\sendmail\sendmail.exe\" -t"

• Open sendmail.init in C:\xampp\sendmail\sendmail.ini, find and update:

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
auth_username=[email protected]
auth_password=password
force_sender=[email protected]

Now you done, remember restart xampp. Good luck!!!
