Step 1:

  • Go to C:\xampp\sendmail: open sendmail.ini file in notepad or any text editor and make the changes as follows.
    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 assword in auth_password: auth_password=*****

    write your gmail id in force_sender: *****
    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 thee error occurred.

Note: Here the procedure is shown for gmail, but it can be extended to other mails by changing the smtp server, port number. When using gmail take care to enable the option to allow access to less secure webapp.
