A person had 2 email adresses, one now discontinued, but on sending to the working one a non deliverable msg comes back, even with adress books checked and auto
Of two different addresses to the same person formerly in my address book, one has been deleted and removed from address books. I am using IMAC. When I send an email to the first address it is received but an undeliverable message comes back later re the already deleted one. Also, I recently got a smart phone and emails sent from it have the same issue, and this phone never had the second address. Thanks!

The problem may be related to my provider as the Mailer Daemon came from them. Apparently the other person saw these duplicates even before shutting that work address recently, so I may have been looking in the wrong place. Thanks for your help.

Thunderbird does not run on phone so I wonder why you think this is a Thunderbird issue. Sounds to me like they have their working address forwarded to the deleted address.
Thanks for your response. I have 2 computers and the phone receiving and sending emails via IMAP and this could be the way my phone gets a bounce on a removed address. I even removed the only remaining address to that person and autocomplete found it. I had a blue screen on my laptop and my problems may relate to that and why I turned off autocomplete.
You have two address books. The personal and the Collected. All suggestions come from your address books so the old address is still in one of them. But this would have nothing to do with what you are seeing. Thunderbird did its job delivering the message to the working address. Tell the other person to cancel forwarding to the old address.
