SpamCop RBL Listing (Resolved) Issue / Performance
10 days

As of 2:30 PM EST the IP address has been removed from SpamCop. We will not resume routing mail through it for the time being (many email operations cache DNS lookups, particularly from dangerous sites) 

Update 04/05/2021 18:09 PM 10 days

One of the IP addresses in our outbound grid ( has been listed in SpamCop RBL.. This is rather unusual for a number of reasons, but the IP address delisting has been completed. The IP address was removed from the rotation so it doesn't inconvenience the existing clients (as many places have SpamCop listed IP addresses set to bounce).

We are still investigating the original issue that caused the listing.
