SPF/DKIM/DMARC Email Deliverability Resolver — Australia

Restore trustworthy inbox delivery for Australian domains by correcting SPF, DKIM and DMARC so customers, clinics and suppliers actually see your mail. We configure authentication ourselves—no freelancers, no bidding—so marketing mail, invoices and appointment systems stop dying in junk.

What You'll Get

• Authentication health audit - Live checks of SPF syntax, DNS lookups, DKIM selectors, DMARC alignment and common provider behaviour (Gmail, Microsoft 365, Yahoo).
• Correct SPF construction - Flattened, valid include chains for your real senders (transactional, CRM, accounting, bulk) without lookup overruns.
• DKIM key & selector setup - Working public keys, selector naming that matches your ESP or on-prem relay, and signing verified end-to-end.
• DMARC policy path - Start-safe monitoring (rua/ruf) through to enforced reject when volume and alignment are healthy.
• Deliverability proof pack - Before/after headers, spam-filter results and a plain-English owner guide for whoever manages DNS next.
• Optional multi-sender map - Document every authorised source so EOFY campaigns and freight-season blasts do not break SPF again.

Serving Australia & surrounds

Remote configuration for Australian organisations whose mail must clear both consumer ISPs and corporate filters—from CBD professional suites to industrial dispatch offices and strata commercial floors. We work around registrar lock windows and change-control calendars common to multi-tenant buildings and franchise networks.

• High-street retailers and café groups whose booking and loyalty mail gets bulk-classified after a host move
• Warehouse and freight operators near precincts such as Dandenong whose ASN and invoice streams must stay out of spam during peak shipping weeks
• Fully remote DNS and M365/Google Workspace changes nationwide; on-site only if your IT policy requires a supervised console session

How We Work

1. Step 1: Reach Out - Tell us the domain, who sends mail (website forms, Xero, Mailchimp, M365, clinic software) and which inboxes are rejecting you—we listen first.
2. Step 2: Tailored Plan - Fixed-scope quote for audit-only, single-domain deploy, or multi-sender enforcement with reporting.
3. Step 3: We Deliver - We implement DNS and mail-signing changes remotely, test against major providers, and document every record.
4. Step 4: Confirm & Follow-up - Plain-English handoff, optional DMARC report review session, and a short stability check after policy tighten.

Common Issues & How to Fix Them

These are patterns we see repeatedly on Australian SMB and clinic domains—symptoms first, then safe checks you can run before escalating.

Gmail or Outlook junk with SPF “permerror” or too many DNS lookups

Often the registrar still holds an old cPanel include while Microsoft 365 or a marketing tool was added later, so SPF exceeds 10 lookups and providers treat the result as unreliable.

1. Step 1: Run a public SPF checker on your root domain and note “permerror”, void lookups, or more than 10 mechanisms.
2. Step 2: List every real sender, remove dead includes, and flatten or use a modern redirect/include strategy that stays under the limit.
3. Step 3: Send a test to a Gmail and an Outlook.com address; inspect Authentication-Results for spf=pass and confirm the message is not quarantined.

DKIM fails after a Microsoft 365 or Google Workspace migration

Selectors in DNS still point at the old host, or the new tenant never published the CNAMEs, so signatures verify as fail even when SPF passes.

1. Step 1: From a received message, open full headers and find dkim= and the s= selector name.
2. Step 2: Confirm the matching TXT/CNAME exists at selector._domainkey.yourdomain and republish the provider’s exact record if missing.
3. Step 3: Resend and verify dkim=pass with body hash intact; if only relaxed alignment is needed for DMARC, confirm d= matches your organisational domain.

DMARC stuck on p=none with zero rua visibility while spoofed mail still arrives

Policy was published for “compliance theatre” without a working reporting address, so nobody sees aggregate fails before a brand-spoof wave hits customers.

1. Step 1: Check DNS for a DMARC record at _dmarc.yourdomain and whether rua= points to a mailbox you actually monitor (or a report service).
2. Step 2: Fix rua/ruf, keep p=none until reports show aligned pass rates, then step to quarantine with a percentage rollout.
3. Step 3: After one to two report cycles, confirm legitimate streams still pass and only unauthorised sources fail before moving toward reject.

Expert insight (Australia): Before EOFY and major retail catalogue weeks we often see domains that “look fine” in a basic SPF tester yet fail Gmail because a secondary CRM include was added without flattening—permerror spikes exactly when campaign volume rises. Good looks like a single authoritative SPF under 10 lookups, DKIM pass on every production selector, and DMARC rua you actually read; bad looks like stacked legacy includes, a selector that 404s in DNS, and p=none with no reports while customers still get spoofed “invoice” mail.
