SPF/DKIM/DMARC Tools

SPF/DKIM/DMARC deployment tools fall into 2 categories: generators (creators/builders) to generate records and checkers (validators/testers) to look up the DNS.

SPF Tools

To create/generate an SPF record, there is the SPF record generator, or SPF record creator/builder, which takes these mechanisms and qualifiers: mx, a, ip4, ip6, include, and all, and returns an SPF record.

To check an SPF record, there is the SPF record checker, or SPF record validator/tester, which checks if an SPF record is published on your domain, and if its syntax is correct.

DKIM Tools

To create/generate a DKIM record, there is the DKIM record generator, or DKIM record creator/builder, which takes a domain and a selector, and returns a DKIM record.

To check a DKIM record, there is the DKIM record checker, or DKIM record validator/tester, which checks if a DKIM record is published on your domain, and if its syntax is correct.

DMARC Tools

To create/generate a DMARC record, there is the DMARC record generator, or DMARC record creator/builder, which takes these tags: p, rua, ruf, sp, adkim, and aspf, and returns a DMARC record.

To check a DMARC record, there is the DMARC record checker, or DMARC record validator/tester, which checks if a DMARC record is published on your domain, and if its syntax is correct.

  • cannot import name ‘_ED25519_KEY_SIZE’ from ‘cryptography.hazmat.primitives.asymmetric.ed25519’ (/www/server/panel/pyenv/lib/python3.12/site-packages/cryptography/hazmat/primitives/asymmetric/ed25519.py)

Solutions:

  1. Try restarting aaPanel and check.
  2. If it does not work, use the ssh tool to execute the following command:

bt restart
