How to remove delivery notifications from smtp@mail with 22.0.330

I recently upgraded Invantive Query Tool and Data Hub from an unknown previous version to 22.0.330.

I’m using the smtp@mail in a lot of automated scripts.

Since this upgrade, each time my script sends an email, I get mail delivery acknowledgement sent to the from field of my statement.

I use for example this kind of statement Tables replication automation with stored procedure giving statistics & error handling by email in the object description, I cannot find a field or option to deactivate this delivery notification.
