Google Workspace Email: Exact DKIM, SPF, and DMARC Settings
Set up Google Workspace the right way: one SPF with include:_spf.google.com, a 2048-bit DKIM key at google._domainkey, and a strict, report-ready DMARC policy with alignment. Start at p=none to discover stray senders, then ramp to quarantine and reject. Verification steps and copy-paste examples included.
