Domain sends mail but can't receive bounces
Check id: mx.missing_but_sends · fix effort: medium
What it means
Your domain sends email but can't receive any. Bounces, replies, and DMARC reports all go nowhere, and that hurts your sending reputation.
The technical detail
SPF or DKIM indicate outbound mail but there's no MX and no null MX. Undeliverable bounce handling drags deliverability down.
How to fix it
- Add MX records if the domain should receive mail.
- If it's send-only by design, publish a null MX (
0 .) and use a reply-to on another domain. but be aware some receivers penalize send-only domains.
