Domain Mail Migration to Stalwart with SPF, DKIM and DMARC

I moved the mail for my business domain, extrovertednerd.com, off a hosted provider onto a Stalwart mail server I run, with Cloudflare DNS, SPF, DKIM, and DMARC tightened for production sending.

Planned and executed the MX, SPF, and DMARC cutover, keeping rollback records until delivery was verified

Activated DKIM, ran round-trip deliverability tests, and cleaned up leftover DNS records

Documented client settings (IMAP 993, SMTP 465) and retired the old mail path

Domain mail on infrastructure I control, with passing authentication and a clear operations runbook.
