No action is required on your part. Delivery attempts will continue for some time, and this warning may be repeated at intervals if the message remains undelivered. Eventually the mail delivery software will give up, and when that happens, the message will be returned to you.

You seem to be talking about sending an email to a person which worked ok in the past but now you get a specific message from the server when you attempt to send to that person.
This has nothing to do with Thunderbird. So there's nothing to fix in Thunderbird.
The server sent a message to you and it tells you the reason. Messages from 203.42.40.145 temporarily deferred due to unexpected volume or user complaints
Suggest you start off by seeing if your IP address and also check your email address to see if it's been blacklisted. TRy spamhaus :
