About SORBS Spam

The SORBS spam zone lists IPs that delivered mail to addresses SORBS runs purely as traps. Any mail to a trap is treated as spam, so this usually means a list-hygiene or compromise problem.

Why an IP gets listed

  • The IP sent mail to a SORBS spam-trap address.
  • A purchased/scraped list contained trap addresses.
  • A compromised account is blasting mail.

Before you request removal: fix the root cause first — delisting while the problem persists almost always leads to a fast re-listing. Confirm the IP has valid reverse DNS, and that your SPF, DKIM and DMARC are in order.
