Remove leftover SendGrid references after the Brevo migration was completed: - Delete TF `cloudflare_record.mail_domainkey` (TXT at `s1._domainkey`, SendGrid-era DKIM, hidden behind the SendGrid CNAME but would re-emerge once the CNAME is removed). - Clean up commented-out `smtp.sendgrid.net` relayhost references and the `# For sendgrid` comment on `sasl_passwd` in the mailserver module. DNS records deleted out-of-band (not TF-managed): - CF: `s1._domainkey CNAME` + `s2._domainkey CNAME` → sendgrid.net (manual entries) - Technitium internal `viktorbarzin.me`: `em7107`, `s1._domainkey`, `s2._domainkey` CNAMEs → sendgrid.net Verified end-to-end mail flow unaffected (Brevo outbound + IMAP receive, roundtrip 20.4s — identical to baseline). Active DKIM (`mail._domainkey` local + `brevo1/brevo2._domainkey` Brevo) untouched. |
