    translation: pt-BR: small wording changes (#552) I'd like what @D0LLYNH0 who's been maintaining the pt-BR translation thinks 1. Excluir -> Apagar, so that if we need to use the word exclude at any point, it doesn't collide with that 2. Signatário -> Assinante, because it's simpler, less of a scary term, and is also valid

DKIM Verifier Reviews

More Email Security Tools

  • Mail client add-on, enabling the use of OpenPGP to easily encrypt, decrypt, verify and sign emails. Free and open source, Enigmail is compatible with Interlink Mail & News and Postbox. Their website contains thorough documentation and quick-start guides, once set up it is extremely convenient to use.

  • Quick tool, that enables you to test whether your mail client "reads" your emails before you've opened them, and also checks what analytics, read-receipts or other tracking data your mail client allows to be sent back to the sender. The system is open source (on GitLab), developed by Mike Cardwell and trusted, but if you do not want to use your real email, creating a second account with the same provider, should yield identical results.
