Errors
Email & DNS Error Message Fixes
Paste the bounce or dashboard error into Google, or start here — we grouped the usual suspects.
DMARC Policy None
You’re only watching — nothing gets blocked yet.
SPF PermError
Fix a broken SPF or trim lookups before receivers rage-quit.
DKIM Signature Failed
Bad key, wrong selector, or something mangled the body.
DMARC Alignment Failed
From: doesn’t match the SPF or DKIM domain — tighten auth.
Emails Going to Spam
Chase reputation, auth, and content — in that order.
Blacklisted IP
Delist, then warm the IP so you’re not “that” sender.
550 5.7.1 Rejected
Decode the SMTP tantrum and patch the real cause.
DKIM None
No signature at all — turn on signing or fix DNS.
PTR Mismatch
Your IP’s hostname doesn’t round-trip — fix rDNS.
No MX Record
Inbox can’t exist — add MX or point mail elsewhere.
