Thunderbird Форум

I'm having issues with my server connection for Thunderbird. I have several email accounts tied to it but only 1 email account is not working properly. I'm able to log in but then shortly I get an error message that it can't connect to the server. The stored password is correct although at one point when I checked there were random letters/numbers in the password field and I changed it back to the former password.

get Thunderbird Error message - 'Sending of the message failed. Certificate key usage inadequate for attempted operation. The configuration related to 127.0.0.1 must be corrected"

     when trying to send a message via Proton Mail's bridge.

grateful for a clue as to what this means, and how to deal with the issue.

Many thanks.

I am starting to plan my upgrade from Thunderbird 52.9.1 to 115. 115 seems a little immature at present, so I'll be waiting until the new year before I do the upgrade but there are a lot of issues so I'll need the time to deal with those anyway.

I have 11 email accounts. Half of those have S/MIME certificates which I get from actalis.it. They are free and have to be renewed each year. Each year a new certificate is created and imported in to Thunderbird.

I use an add on called "security settings from address book" which allows me to automatically encrypt emails to recipients who have a flag set in the custom fields. This addon is not supported in Thunderbird 115, but I'm hoping the new certificate functions in 115 will work. I will not be using OpenPGP, Enigmail or GNUPG.

As each email address gets a new certificate each year I have to import each certificate to be able to access these older emails. So my question is this;

I assume if I don't import the certificates for each account for every year I will be unable to access the emails that were sent/received during the valid period of the related certificates - is that correct?

How will this affect people with whom I sent/received encrypted emails? Are they going to have to upgrade to 115 at the same time? I would have thought that as long as they have their certificates already installed in the same manner in which I had in my old Thunderbird they would not have to do anything?

Unrelated to encryption/digital signatures, I've just had a thought... Am I going to come across any issues pointing Thunderbird 115 to my existing mail folders?

I believe there is no "upgrade path". I have to do all of this from scratch?

I have about a 1,000 filters. Everything gets moved out of the inbox for the account into one or more folders on the Local Folders, where all of my mail folders reside. Can I copy the msgfilters.dat file for each account to the new installation and it will work? Or am I going to have to create all of the filters from scratch too?

thanks.
