Where is the Alert & Respond Email/SMS Configuration information stored?

[Denise.Perrotta]

Hello all, hoping someone can help me. We are setting up IAM User Keys that are supposed to rotate on a monthly basis. We use those keys to send email from AppDynamics. I can connect to the SMTP server just fine. What I need to find out is where is this information stored so that I can create a script that will update that information when the keys get rotated. Is it in the database, and if so what table? Or if its in a file what file? Thanks for any and all help!
