Mozilla Thunderbird Outgoing Mail Blocked

JMMinColorado

My outgoing mail is blocked. I have another computer that has identical outgoing mail settings and uses the same ISP. The mail on the computer works just fine. The only difference that I know of is I have bit defend her on my computer.

Mozilla suggested that I start my computer in safe mode. However, in doing that I have no Internet even though I selected the safe mode with Internet option. I have a Lenovo computer.

Is there a way to completely disable all features of Bitdefender?

Hello @JMMinColorado and welcome to the Community!

Yes, there is a way to disable the security modules one by one to check which one is blocking the outgoing e-mails.

You can check the article below for steps on how to do this:

Make sure to enable them back on afterwards.

Then, you can also check the Online Threat Prevention module settings, specifically e-mail protection:

Let me know if this helps.

Best regards.
