Sounds like a problem with PGP/GPG as if the it can't import keys or decrypt message or verify signed message.

So do you use encryption?

No.

No.

At least I don't remember having done anything to activate it, but may be some default options are activated. But I don't have a pgp key configured for my account. But I sometimes receive pgp signed emails. Maybe I opened a signed email before trying to reply to another and got this error.

The problem is the Autocrypt header of the email. When you reply, the Autocrypt header is parsed and the PGP key is imported on the server and in OpenPGP.js

https://github.com/the-djmaze/snappymail/blob/614c7ace445074ff20f7a8d3f6afbb8eba151f73/dev/View/Popup/Compose.js#L914-L921

So something is wrong with the Autocrypt header. Can you forward such email to me? To issue-1608@snappymail.eu is fine

Can you forward such email to me?

I sent by email the problematic Autocrypt header to you. Let me know !

the-djmaze commented 1 month ago

Could you send the whole message and not just the Autocrypt header?

Massedil commented 1 month ago

I just sent you a whole message that triggers the problem described here. Let me know !

The Autocrypt header ends with nrzCXopEosI= But the javascript code .split('=') and .split('=', 2) dropped the last = and failed.
