We have recently installed Bugzilla on IIS6.0 in windows 2003 Server. Everything is working fine except sending email. We have configured SMTP email configuration. We provided the smtp server, user name and password. Still Bugzilla is not able to send an emila and reports "Could not authenticate the user". When the same details are provided to a different application, the emails are going smoothly.
Any help in resolving this issue is greatly appreciated.
