CNC-SDS-0408 There are email messages waiting to be sent

Hi Guys

I am facing this issue today .. so havent figured out much yet.Will post as soon as i manage to solve this

CNC-SDS-0408 There are email messages waiting to be sent.

Problem(Abstract)
Scheduled reports fail to send by e-mail even though the SMTP server tests fine in Cognos Configuration. Multiple error messages are generated.

Symptom
CNC-SDS-0408 There are email messages waiting to be sent.
CNC-SDS-0410 The email message was not sent. Approximate message size: [59 KB] The Mail server returned this error: [530 5.7.1 Client was not authenticated ]
CNC-SDS-0335 Error returned from SMTP Server. The error message was: [530 5.7.1 Client was not authenticated ]. The message could not be sent.

Cause
By default, SMTP servers are configured to block any relay messages from servers which are not on the authorized list. This is to prevent any unauthorized sender to send messages through that server.

Resolving the problemOn the SMTP server, add the IP of the Cognos application server(s) to the authorized sender list

Things that can be tried

I am trying to burst a report its giving me the above error .
Step 1
1) Try to create a normal report and schedule it.Send output by mail .If its working then atleast you are sure you have privileges to send mail .Sometimes admin block this privilege so just check to be sure.

I checked it and found its not happening .Contacted my cognos admin team and guess what the dev server does not have mail server configured :-) .
