> I must admit that when I send a really important email, I check the mail server log if it went off without errors, but this does not bother me as checking logs manually once in a while is a good thing anyway.

I also self-host my email. It would be very nice if there was some sort of notification system that alerted you if your email got bounced by the receiving server. A notification that fed through into Thunderbird would be marvelous.

Well I don't know if you wrote this in a sarcastic way or not, but when you write a new message in Thunderbird just turn on `Options -> Delivery Status Notification` and your mail server will email you back with a delivery status message (success or failure, although failure can take some days if the receiving server doesn't outright reject your message)

I was not sarcastic. I just tried this by sending from my gmail account to one of my other accounts. Didn't get any email back even though the email was immediately delivered.
