Deliverability
IP and domain blacklists
A listing on Spamhaus or a similar DNSBL can reject mail even when SPF and DKIM pass. Check the domain and the sending IP, request delisting only if the listing is real, and do not keep sending through a listed name.
Domain vs IP
- Domain listing — the sending domain (or a URL in the body) is on a blocklist.
- IP listing — the sending address is on a blocklist. Hosted EmailPal mail uses isolated IP pools.
A new domain can show up on some lists simply for being new. That is annoying and usually temporary. A listing that cites spam traps or stolen lists is not temporary — retire the domain.
What to do
- Confirm the listing on the blocklist's own lookup, not a screenshot from a sequencer.
- Stop sending on that domain or IP immediately.
- If it is a hosted EmailPal IP, open a ticket. Do not open delist requests on IPs you do not control.
- If it is your domain, follow that list's removal process once the abusive sending has actually stopped.
- Verify the list that caused it before you touch a new domain. How to verify an email list before sending.
FAQs
Should I buy a delisting service?
No. Most are unnecessary. The list operator's form is the path.
Does warming get me off a list?
No. Warming builds reputation. It does not file a Spamhaus ticket.
