Thunderbird 78.4.3 email fetching problem

[notuo 1]

Hi.

Yesterday I update Thunderbird to version 78.4.3 and today I update My ESET Internet Security to version 14.0.22.0

The issue is I cannot fetch any emails from my own servers (STARTTLS)

I followed the procedure in this topic:

and here is the zip file from log collector

Only when I disable the Email client protection I am able to fetch my emails.

Any advise is appreciated,

Hello @notuo,

I would start with:

• Disable the SSL/TLS filtering in the ESET GUI
• Reboot the system
• Change update type to pre-release
• Wait until the update finishes and make sure you have Internet protection module 1414
• Enable the SSL/TLS filtering in the ESET GUI
• Check if you are able to fetch the e-mails in Thunderbird.

 

If not 1. is the certificate used to secure the connectivity to the e-mail server trusted by the system on which you run the Thunderbird? 

If not import it to be trusted and try to fetch the e-mail again.

 

If even that won't help provide us with a fresh set of logs recorded with the Internet protection module 1414

If you are not running any mission critical applications on the machine, I'd recommend keeping pre-release updates enabled. However, if you don't want to receive program and module updates among first, switch to regular updates after 1-2 weeks.

Thanks Peter. This worked fine.

Hi,

I made this steps, but internet protection modul has version 1417 (not 1414) - and it still doesn't work.

Thundbird asks me for dialog "Adding of security exception".

It it neccessary to downgrade IPM to 1414 ? If yes, then how to do it ?

Thanks.

Regards

Jan

What version of Thunderbird do you have? Could you confirm it's not a portable version?

Following the instructions at https://support.eset.com/en/kb7728 didn't resolve the issue?

Make sure that after disabling SSL filtering there is no ESET root certificate in the Thundebird's authorities certificate store. After re-enabling SSL filtering, an ESET root certificate will be added:

Not necessary, the latest module is ok.
