These alerts not coming from production database.
Initially thought this is from production. After that based on the data we realized it is not from production.

So we disable jobs (PMDR Import SSIS Job) in new and old QA servers . after disable job in QA server mail alerts are stopped.

So these alerts are coming from one of the QA database.
