To be precise: 1. But I get a lot of penis enlargement, and blue pills offers. Also requests to "verify" my address to receive packages, I'm not aware of.

The issue is, that most effective traditional e-Mail spam filters introduce delays, that many users deem unacceptable for a chat.

@cdonat are you using a classic email address or a chatmail relay? Chatmail relays don't allow unencrypted messages, which filters out spam completely. But a chatmail relay address will only be able to talk to Delta Chat users, not classic email users. Here you can pick one: https://chatmail.at/relays

I'm using a normal email address. And for the time being it'll stay that way - for different reasons. Though it is a mail address, I exclusively use for Delta Chat.

If you are aware, what I could add to my procmail file, to also filter out non-encrypted messages, that would be a huge help.

Instead of using the inbox you could use the DeltaChat folder - somewhere in the settings of the deltachat client.
Otherwise, you'll need to fight the spam with your email provider. Its not related to deltachat.

How does the mail get into that DeltaChat folder? How does that get rid of the spam?

About where I'd have to change things: guess why I asked for any knowledge about the procmail file for DeltaChat. That is a standard way to tell a mail server, how to handle incoming mail.

Yes, that could also move mail to the DeltaChat-Folder, BTW. But it has to know which.

Not sure if your provider allows it but you could add a sieve filter and move your specific emails to the deltachat folder automatically.

And how do I detect non-Spam messages. That is the question.

@cdonat @delta
Do you use delta chat as your email client?

It sounds like you get a lot of spam and your email provider can't handle it. Might be better to use another email provider. It's also good to change your email address every now and then.

But to answer your question, you'll need to adjust the sieve filter yourself. Whatever most wording you have in your spam mails you create/adjust your sieve filter.

No, I don't use DeltaChat as my email client. In my normal mail-account I have quite some spam filtering active, but that adds latency, that generally isn't accepted in a chat by my communication partners.

I have an email-address, that is exclusively used for DeltaChat. I partially own my email provider, and therefore won't use a different one.

And the real question, you didn't answer again: how do I distinguish valid DeltaChat messages from spam?

1/2

Before @delta responded, that a Chatmail-server only forwards encrypted messages.

So it is possible to detect valid DeltaChat messages by looking for encryption with relative ease. Therefore it should as well be possible to implement that with procmail, or sieve.

My only question is how to do that detection. As soon as I have that, I can adapt the procmail file myself.

Alas you're just adding useless noise. I get, that you''re trying to help.

@cdonat @digitalprivacy chatmail relays use this small rust program to filter out unencrypted messages: github.com/chatmail/filtermail
you can hook it into postfix like this: https://github.com/chatmail/relay/blob/main/cmdeploy/src/cmdeploy/postfix/master.cf.j2
