Rated 3 out of 5 stars

Thanks to the developer for this excellent addon! I've been using it for some time now with great pleasure. However, since switching to Thunderbird Supernova, it's been catastrophic. Every time I redirect a mail, a popup window opens telling me that there's an SMTP error and that the message has failed to be sent, with the words "Service closing transmission channel". As I redirect a lot of emails, I'm constantly disturbed by multiple popups to close. The worst thing is that my messages are properly redirected. When I tried to downgrade Thunderbird to the previous version, the problem disappeared! I reinstalled Thunderbird and the addon, without success. I don't know what else to do... Thanks for your help.

This review is for a previous version of the add-on (1.34). 

I can't reproduce your problem with the current TB 115.2.3.
Are you using a beta version of TB?
