Hello everyone,

I'm experiencing problems using mailing lists in Thunderbird 128.3.3esr (64-bit).

When the mailing list is not expandend i got the error in attachment, it only work if I expand the list.

Any advice ?

Thanks for your time :)

There have been other reports of not being able to send to lists unless the list is expanded:

I cannot duplicate this, and am able to send to a list in the usual way. I enter the sending address in the To box and enter the list in the Bcc box: test list <test list>. I also did it as in your picture, sending from a gmail account and just entering the list in the To box. In both cases, the messages are sent and received without errors.

To diagnose the issue, I suggest you run TB in safe/troubleshoot mode, and if the problem remains, test with a new profile created from Help/Troubleshooting Info, about:profiles.

Hello,

Thanks for your reply, the safe mode helped me to find the problem, it was caused by this plugin : https://addons.thunderbird.net/en-US/thunderbird/addon/sp%C3%A4ter-senden-button/.

Have a great day.
