Antispam
Antispam
Constantly Prompted To "add Security Exception" By Thunderbird
Windows 8.1 x64 Pro
Bitdefender Total Security 17.25.0.1074
Thunderbird 24.3.0
I think this has been discussed before, but I can't find any resolution.
Whenever Thunderbird tries connecting to my IMAP server, I get prompted to "Add Security Exception", because the "Certificate belongs to a different site, which could indicate an identity theft." The same dialog says "Certificate is not trusted, because it hasn't been verified by a recognized authority using a secure signature."
Keeping "Permanently store this exception" and selecting "Confirm Security Exception" does not work. The prompt appears every time regardless.
Disabling the BD toolbar Thunderbird extension and the Anti-Spam module does not prevent this problem.
Is it true that BD's entire anti-spam module (not just the toolbar) does not support IMAP?
Is there any way to make this aggravating dialog go away, without totally removing BDTS?

Hi heterodox
As you surmised, Bitdefender Antispam does not support IMAP. You'll need to disable the BD Toolbar form Thunderbird Tools/Add Ons and then disable it from the BD Console (if you still want to try to keep Bitdefender). It's been a desire from those in the past to include the IMAP functionality, but for now, it's just POP/SMTP0 -
Thank you for the reply, but I have the BD toolbar disabled in Thunderbird, and I have Anti-Spam disabled in BDTS, and I still get these dialogs. This is why I asked if it is possible to resolve this problem short of totally removing BDTS. I never got these dialogs before installing BDTS.

Apologies for missing that on your original thread, I was to focused on the IMAP not being supported.
Try this, and see if this helps: http://forum.bitdefender.com/index.php?s=&...st&p=1572280 -
I deleted the "bdThunderbird@bitdefender.com" value under "HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Thunderbird\Extensions", and even reverted to an old copy of prefs.js that had no mention of Bitdefender. The problem persists.

I'm not sure what to do next, but maybe wait and see if Georgia has a shortcut fix or an idea for this one, or another member may respond?

I don't think it's a toolbar issue at all. I think it happens when BD intercepts traffic to/from my IMAP server. When I'm able, I am going to try disabling email scanning.

I may have the problem licked. (Not a solution, but a workaround.) I changed from SSL/TLS to STARTTLS, and don't seem to get the prompts anymore, even with email scanning (i.e. antivirus) and anti-spam enabled.
Because I hate when people are vague about how they fixed a problem, here are the rather exact steps in Thunderbird:
1. Select Tools > "Account Settings..."
2. Select "Server Settings" under the applicable account(s).
3. For "Connection security", change SSL/TLS to STARTTLS.
4. Select "Outgoing Server (SMTP)".
5. Double click each applicable SMTP server, and then perform step 3 for it.
6. Click OK twice.
Thank you for trying to help, Scott. I really appreciate it.0 -
You might be able to resolve this by going into Bitdefender Settings-> Privacy Control Settings -> turn "Scan SSL" off
BitDefender is essentially using their own certificate to encrypt/decrypt web and email traffic if this setting is enabled. For some reason (looks too much like a "man in the middle" attack?), the OS and the browsers don't like this behavior or don't recognize the Bitdefender certificates.

You're welcome heterodox, sorry I could offer only little help, but your appreciation is accepted
It sounds like you're a step or 2 more proficient in your PCing skills and knowledge than I am, so thanks for posting your solution as it could help others here in the future.0 -
This is an old topic, but my answer might help someone.
I had the same Security Exception problem, and it turned out to not have anything to do with Bitdefender. When I set up the new IMAP account I had Thunderbird automatically pick the settings, including the servers (as suggested by my provider.) I went back to my provider and got the manual settings, changed the incoming server, and the Exception problem went away.0 -

The key thing would be when the problem started: Immediately after setting up a new email host in Thunderbird, or immediately after installing BD.
I have not been using BD since running into all those problems last year. I just installed BDTS 2016, and this issue cropped up anew. It most definitely has everything to do with BD on my setup. I own my own domain and I know what the proper settings are.
The STARTTLS workaround still seems to work, but it's frustrating that BD still has this issue.0
