Overview

UCEPROTECTL1 (dnsbl-1.uceprotect.net) is uceprotect.net’s primary level zone. If your IP is listed here, it typically means you have either had an open relay or you have a reverse-DNS problem. Once corrective action has been taken your IP should be delisted in seven days.

How it works

UCEPROTECTL1 lists IPs based on the following criteria:

• If a set of IP addresses is flagged, it will start with a listing in the level one list. IP addresses can be flagged for the following reasons:
  • Unsolicited Bulk Email (UBE) in their Spam traps. This could be a result of a compromised email account, an Open Relay, or simply sending mass emails / marketing and not following best practices.
• If within seven days, that spam has not stopped, the listing will escalate to contain much broader ranges of IP addresses

Remediation

UCEPROTECTL1 listings and delistings are automated so removal will typically happen automatically after corrections have been made and the IP addresses are no longer flagged. More information about UCEPROTECTL1 can be found at their website: http://www.uceprotect.net/
