[CC][C8]Problem with email sending in Cognos 8.4.1

[techFanatic]

Hello,Im facing problem in emailing reports.I have done the following changes in the cogconfigw.exe file in Cognos Configuration
a)Added the SMTP server and tested the connection.It tests successfully and sends a testmail to the notification sender configured.Also I have verified that the SMTP server is allowed to send email via telnet. 8)
After doing this I scheduled the report to run and be attached in an email,but I got this error message CNC-SDS-0408 There are email messages waiting to be sent.  :o after the scheduled period had passed. :(

b)So after this i configured the Notification component same as the Content Manager-Cognos Content Store and tried running the schedule.Still was unable to send the email with the same error as before. :-\ :(
The Content Manager-Cognos Content Store and the Notification component has default settings enabled and successfully test. :)
Please do notify me about any mistakes done in the process of configuration or if any other settings are needed to be configured.I have a feeling that the notification component is wronly configured.Your feedback will be helpful.
