Currently I’m trying to set up Deltachat communication with people living in a country with internet censorship that might be trying to block common messengers. I’m not sure how deep they are looking into the data stream, but I have to consider them filtering email traffic. Therefore I’d like to know whether it’s possible to tell apart Deltachat messages from common PGP encrypted mails by analyzing the headers. On the first glimpse at the headers I found nothing, but I’m not an expert. Could you please give me a clue?
Thanks in advance
