Issue:
Does Cognos BI send a mail when you click on TEST of notifications i Cognos Configuration?

Solution:
Yes, cognos configuration test mail function, will send a mail to the default sender with the default sender as sender.
If you enter a valid mail address at the company as the default sender, and click test, that person will have a mail.

Under Data Access – Notifications set it up like this:
SMTP mail server: smtpserver.company.com:25
Account and password: (can be blank if the SMTP server allow resend of anonymous mail)
Default sender: roger@company.com (use the mail address to a person at the company)
