First you need to generate a private and public key for DKIM:

```bash
openssl genrsa -out dkim.key 1024
openssl genrsa -traditional -out dkim.key 1024

@nguyenkims since dkimpy v1.1.0, PKCS#8 is supported. What about you increase the minimum version instead?

Do you know if it's compatible with the old key that people generated? I want to make sure that when people upgrade SL, they don't have any issue.

It's a try/except trying the old key standard first so still compatible :D.

openssl rsa -in dkim.key -pubout -out dkim.pub.key
```
Note: the `-traditional` flag is only needed if using an openssl version > 3.

You will need the files `dkim.key` and `dkim.pub.key` for the next steps.

I agree with @hoyohayo : if using an open resolver almost every email would get blocked (https://www.spamhaus.org/news/article/788/spamhaus-dnsbl-return-codes-technical-update) and the standard return codes are available here.

I confirm an error when using open resolvers, here is the error:
554 5.7.1 Service unavailable; Client host [xxx] blocked using zen.spamhaus.org; Error: open resolver; https://www.spamhaus.org/returnc/pub/172.71.133.37;
I'm using google DNS for my docker as recommended workaround here
https://www.spamhaus.com/resource-center/successfully-accessing-spamhauss-free-block-lists-using-a-public-dns/
but I don't really like using google DNS...

@Metabaron1 I would recommend something like this alongside a PTR and you're good to go ;)

To run SimpleLogin, you need a config file at `$(pwd)/simplelogin.env`. Below is an example that you can use right away, make sure to

- replace `mydomain.com` by your domain,
- set `FLASK_SECRET` to a secret string,
- set `FLASK_SECRET` to a secret string (e.g. generated by pwgen `pwgen -B -s -y 64 -N 1`),
- update 'myuser' and 'mypassword' with your database credentials used in previous step.

All possible parameters can be found in [config example](example.env). Some are optional and are commented out by default.
