Problems with Thunderbird email client caused by Vade Secure Cloud security

[bigjohnnym]

Is anybody having problems, as of last night, with something called Vade Secure messing up all talktalk emails? Or is this a Thunderbird problem?

@bigjohnnym, I would like to point out my appreciation of the information you are currently providing to us as this will assist many of our clients. 🙂

Just in case you don't know, Bit Defender has confirmed they've reverted a recent update which caused this problem. It is wise to run a BD manual update unless you've done one in the last day or so, to ensure you've got the latest version, and then check you've got "Encrypted Web Scan" turned on if you temporarily turned it off.

There's not much I can do if you using client to access your emails, I would advise you use webmail till this is sorted out. Thanks

thats fine for thunderbird, but i am using outlook, email for mine and it lt applies to email coming in on my talktalk address  and server only not in my gmail.

[siphosethu-TT]

Hi there @bigjohnnym, when you say quickly I got my fingers crossed. Thanks

[bigjohnnym]

I agree, but it works until Bit Defender fixes the bug.

I had a conversation yesterday with UK Bit Defender support, and sent them diagnostic info. The support guy was apparently aware of some sort of problem, so he said he would escalate it from his end.

I think they will fix it pretty quickly, as there have only been small updates for a while now.

@bigjohnnym 

That should be viewed as a temporary solution, unless you are happy to turn off real time scanning of web traffic, or have some other application doing that.

Thank you for sharing this information @bigjohnnym, I hope it is helpful to others as well.

Hi, people!

I asked the question on the Thunderbird community/support site this afternoon, and a very helpful guy called Wayne (I'm sure he's helped me before)  suggested the cause / solution. I'm using Bit Defender security software, which he suspected, and he suggested I should change a setting within the ONLINE THREAT PROTECTION: Change the Online Webscan from On to OFF. I guess it conflicts with their existing cloud-based systems. Restart the PC, Start up Thunderbird, and (if you like) send yourself  a test message. Voila! Problem solved!

i also am having the same problem in outlook mail. 

X-VadeSecure-Status: MC, plus who the email is coming from , i have had 20 so far.

[RodWood]

I am having same problem. Does anyone know what the fix is? Thanks

[Mandisa-TT]

Please do not hesitate to reach out to us in the future if you require any assistance. Best regards.

[bigjohnnym]

No thanks, Mandisa. 

Cheers

[Mandisa-TT]

Is there anything else I can assist you with?

[bigjohnnym]

Mandisa,

Thanks for your efforts.

[Mandisa-TT]

@bigjohnnym I can confirm that there are currently no incidents reported regarding the implementation of an additional cloud security system, such as Vade Secure, by TalkTalk. As of now, there are no known issues related to this matter.

[bigjohnnym]

Mandisa,

I am already doing that, but I needed to confirm that Talktalk had not inplemented an additional cloud security system,  Vade Secure. Can I assume that TT know nothing about this, please?

[Mandisa-TT]

@bigjohnnym Thank you for your prompt response and for confirming that your Webmail is unaffected. I recommend reaching out to Thunderbird, as they may be able to assist you with your query.
