Config bugzilla to send mails with gmail account in windows

1. Download Glob's sendmail program for windows at http://glob.com.au/sendmail/, and unzip it.
2. Copy all items in unzip folder to \usr\lib on the drive where Bugzilla is installed. So if Bugzilla is installed at C:\Bugzilla or any folder on C: drive, create a 'usr' folder at the root level of the C: drive, with a 'lib' folder within that.
3. Open sendmail.ini to edit these values in this file.

    force_sender=email@yourdomain.com


    If you are using gmail

    smtp_port=587
    smtp_ssl=tls
    auth_username=youremail without @gmail.com
    auth_password=yourpassword
    force_sender=youremail@gmail.com
