Newly Observed IP Blocklist (NOIP)

A newly observed IP blocklist is built by storing every IP address that has sent SMTP traffic to our traps or to our partners over the last 30 days.

Any new IPs found in the list that has not been seen previously are listed for 25 hours.

An IP address on this list doesn’t necessarily mean that the IP address is bad, but this is useful for scoring and meta-rules, especially when combined with other data and greylisting or sending a temp fail.
