Nord keeps telling me that Mozilla Thunderbird Version 128.0.1 Severity level : High. Exploiting this vulnerability is relatively straight forward for attackers. They may gain unauthorized access to your data or cause system disruptions. Risk mitigation is needed. This message was also for the latest 115 version. Then I updated to 128 and it has the same problem

Hi E-mail message which i sent via Thunderbird contains in headers my internal and external IP in "Received from" record. Is it possible to hide it without use proxy or VPN? Recipient can see it.

I need to replace the 64-bit Thunderbird with a 32-bit version to sync with a 32-bit application. I have not been able to find a download site which does not require also downloading unknown add-ons. Is there one, or do I just trust my luck?

I'm needing to transfer a fair amount of company email from POP accounts to Gmail for Business.

I understand the typical response is to add the gmail IMAP account to TB and copy the messages.

I've tested this feature and it works great. However I'm unsure of the exact mechanism used. Mainly, is this transportation between servers encrypted?

The gmail IMAP account is setup to use SSL/TLS, port 993 and authentication method is normal password.

Can someone confirm these emails will be protected in transit? Thank you in advance.
