Since today, I'm unable to send mails to mailservers using the UCE Protect Spamlist.

Diagnostic-Code: 5.7.1 Service unavailable; Client host [136.143.188.55] blocked using dnsbl-1.uceprotect.net; IP 136.143.188.55 is UCEPROTECT-Level 1 listed. See http://www.uceprotect.net/rblcheck.php?ipr=136.143.188.55

The whole 136.143.188.0/23 is listed and they require to pay for delisting.

Please fix this asap, as many businesses in EU use that list.
