bug report: DKIM key mismatch

[MarcS1975]

📝 Preliminary Checks

• [x] I tried searching for an existing issue and followed the debugging docs advice, but still need assistance.

👀 What Happened?

DKIM keys say mismatch for every email I send.

Steps i took:

1. log into docker container
2. setup config dkim domain 'mydomain.win'
3. this creates new DKIM keys in /tmp/.... folder
4. remove container
5. recreate container and start
6. confirmed that all files in /etc/opendkim/keys are updated (copied from /tmp folder)
7. Confirmed that DNS records are correct.
8. Sending email gives DKIM error:
9. `Authentication-Results: mail.mydomain.win;

dkim=fail reason="signature verification failed" (2048-bit key; unprotected) header.d=mydomain.win [email protected] header.a=rsa-sha256 header.s=mail header.b=kdlnzb/U; dkim-atps=neutral

Found the problem: the DKIM key that is generated is multiple lines long and although that passes all DNS key checks and DNS providers accept the format as correct, it does not pass a match test between a DKIM signed mail and the DNS record. Only when flattening the key it works. -> strange

You are referring to flattening at the DNS record? That is required for some DNS providers, but doesn't work for others, we document this:
