Blacklist (DNSBL) check
Whether the servers behind your domain are on the SpamCop or Barracuda blocklists, which some mail providers use to reject email.
Check this on your own domain now. It is free with a DomainGuard account and works on any domain. The check reads only what your domain publishes, and gives you a report you can send to whoever runs your website.
What we look at
We look up the single sending addresses your SPF record names and any mail server inside your own domain (or, when there are none, your web server's address) on two DNS blocklists, SpamCop and Barracuda. Spamhaus is not included: its public lists do not allow commercial use without a subscription. A clean result on your website's address is only a rough proxy for your mail, so it is not scored.
Why it matters to your business
A listing means some mail providers refuse or junk your email, often without a bounce, so you only notice when replies stop. Listings usually follow a compromised mailbox or website sending spam, which is worth knowing about for its own sake.
How to fix it
- Find out why: check for compromised mailboxes, contact forms being abused, or malware on the website.
- Fix the cause, then request delisting from each list's removal page.
If you would rather not touch DNS or server settings yourself, forward this page and your report to whoever manages your website, or ask us to do it.
Keep an eye on it
A one-off check tells you how things stand today. On Starter and up, DomainGuard re-checks the domains it watches every day and alerts you in the app when something important changes, so you hear about it before a customer does.
