MailHop IPs on Spamhaus XBL

Some of the IP addresses for our MailHop Relay, Forward, and BackupMX servers have been added to the Spamhaus XBL blacklist because they appear in the CBL blacklist. We have requested delisting from CBL and the are in the process of doing so. Once Spamhaus checks the CBL again, the servers should be removed.

Unfortunately we were given no warning from CBL and have been given no information as to why our servers appeared on their blacklist. We are working to get that information so we prevent this from happening in the future.

Update: Immediately after the original status posting, Spamhaus removed the IPs from their XBL. We will continue to investigate and try to work with CBL to prevent this from happening in the future.

1520 UTC Update: Currently, we are still listed in the CBL via the XBL and are continuing to work with CBL to get our addresses delisted; however our attempts to contact them via e-mail have not yielded a resolution. Please note that if you are a BackupMX or Relay customer and are experiencing issues with this DNSBL, you should use a whitelist to guarantee delivery from our mail server’s IP addresses.

1720 UTC Update: We are awaiting a reply from Spamhaus regarding the situation with being listed in the XBL from the CBL and as of yet, have received no reply from the maintainers of CBL.
