Send mail task it does not allow all the user to run the mail

Hi guys, I'm using the Send Mail Task and it's working but only using my mail. Pratically I set up a connection manager, Use Windows Authentication.  Fromdiegoctn@mycompany.com to diegoctn@mycompany.com . Message: the package ran without problem. That's ok.

But..if I use ssis@mycompany.com to diegoctn@mycompany.com it retrieves the error : Client does not have permission to send at this sender.

My network administrator set up the mail ssis@mycompany .com with the password mycompany01 and it's asking me to find a different solution but I guess there is something that can be done. My purpose is to run the package from every machine and every user within my team and not only from my user.

Any advice?

Thanks
