Hi, after we move on new jenkins server from ver. 1.585 to 2.19.3. I have problem with same job.

On new server job sending duplicate email.

Log from 1.585 - email ext 2.40.5

Email was triggered for: Failure - Any
Sending email for trigger: Failure - Any
Sending email to: emails
Warning: you have no plugins providing access control for builds, so falling back to legacy behavior of permitting any downstream builds to be triggered

Log from 2.19.3 - email ext 2.52

Email was triggered for: Failure - Any
Sending email for trigger: Failure - Any
Sending email to: emails
Email was triggered for: Failure - Any

Warning: you have no plugins providing access control for builds, so falling back to legacy behavior of permitting any downstream builds to be triggered

Configuration of flow is same on both servers.

Thanks for help
