KB15885: MicroStrategy Narrowcast Server does not send the email and no error message is generated in the DELogxxxxx.log file

SYMPTOM:
In Strategy Narrowcast Server, a user has created a service that performs both actions of sending an email and writing a copy of the sent email to disk. A copy of the sent email is created in disk, but the users do not receive the email and no error message appears in the log files DELogxxxx.log and C:\Program Files\Common Files\MicroStrategy\Log\DSSErrors.log.
 
CAUSE:
In this case, the problem is the name resolution because the Domain Name Server configured in the server where the Strategy Narrowcast Server had been installed was not working properly. However, all web connections to external web sites were working fine because the gateway worked fine, but the communication with the mail server did not work.
