Can no longer send BCC'd emails to groups
I had the same problem maybe a month ago but it seemed to fix itself somehow.
When sending BCC'd messages to groups I am now getting a message that particular email addresses are no longer viable and are blocking the sending of the email.
I have contacted people at those addresses and found out there is nothing wrong. The email addresses Thunderbird are saying are bad, are in fact good and receiving single emails from me.
Any known fix for this?
TIA, Gordon

Here is the message I get with the address in question removed.
Sending of the message failed. An error occurred while sending mail. The mail server responded: HVZLnTStgNat4HVZLndRkU internal error. AUP#SMTP. Please check the message recipient "xxxxu@gmail.com" and try again.
And I would like to remind anyone answering the question that all emails are healthy.
The error message might not actually indicate the root of the problem, if all addresses are valid. Who is the mail provider you're sending from, and is the sending account sending through an smtp server with the same User Name, i.e. email address? So, e.g., you're not sending from account X through the smtp with account Y's address.
I am working with Shaw servers
I tried using Webmail and it worked, I think.
Tried again with Thunderbird and got a new response.
Sending of the message failed. An error occurred while sending mail. The mail server responded: <gxxxonsxir@shaw.ca> server temporarily unavailable. AUP#MXRT. Please verify that your email address is correct in your account settings and try again
There are quite a few similar reports on the Shaw support forum, but I haven't seen a clear explanation. As long as the settings are correct for the smtp (mail.shaw.ca on 587, STARTTLS, normal password, User Name = part of address before @), it might matter if the password is not 'strong', according to this article. At one time, a strong password was required to access Shaw accounts with desktop mail apps.
A possible alternative is to use the smtp server for a different provider such as gmail. By adding the Shaw account in gmail webmail settings as a 'Send mail as' address, messages can be sent from Shaw in TB without the Shaw address replaced by the gmail address.
Thanks for the helpful replies. After talking with a support person at Shaw it was determined that the fault does ly with Thunderbird, my email client.
