Recently I stopped receiving Delivery Status Notifications even though I have that checked on every email I send. I have read that some servers will not respond to DSN but I am sending to the same email addresses I had always received DSNs from until about 2 weeks ago. I have tried disabling add on's with no luck. I am using Thunderbird version 86.0b3. I do still receive Read Receipts when I request them & when they are responded to by the recipients. Below is what the notification contents looked like. Any advise to correct this would be greatly appreciated.

from: MAILER-DAEMON@proxyz13.mailnet.ptd.net This is the mail system at host proxyz13.mailnet.ptd.net.

is there some reason you are using pre release software? The current version is 78.
