I do not see that Bitdefender is working with Thunderbird? I thought there used to be something when you right clicked an email that you could scan with bitdefender an individual email if you thought it might be suspicious . There also used to be a spam folder and you could chooe an email and mark it as spam? Now I see no evidence that bitdefender is pre-scaning emails? Can you confirm? I use Thunderbird Version 68.9.0 I use Bitdefender Total Security
