That was my very first attempt. But since these 2 files were of exactly the same byte size, it did not surprise me it diint work.

It seemed to me the .bak file is created every time claws closes ? Then of course it was gone, since i closed and restarted claws several times, in the process of down- and upgrade.

Yes i understood that. As you can figure out yourself now, this is a dangerous thing...

Yes, but my last backup is from 2017, April 11. But then gain, i did not change the passwords since April 11. I sent other mails regarding that, but in short, those passwords do not work anymore. And i really don't know what's going on here. Is it possible they get re-encrypted at some time, maybe when you change anything else in the account (like switch from STARTTLS to SSL or so) ? Or in the process of down- and re-upgrade ? Like, some claws key/Cert has changed ? What if the mailbox providers cert change, could it trigger re-encryption ?
