Hi, before I send the email, I select the delivery status notification dsn from the options and then send the email, so I don't receive any email. I use version Thunderbird 128.2.3esr. Thanks for informations.

DSN is still in the standard and still can be requested by mail clients, but the vast majority of mail servers have it disabled. Fundamentally backscatter was getting them listed as spammers and resulting in their ability to deliver mail being restricted. Disabling DSN stops the whole backscatter problem.
