The graphic shows you the real mailflow of those of our customers that have freely chosen to enable "report statistics" in their appliances / software. Those customers are mostly located in Germany, Austria and Switzerland. This is how we are counting ACCURACY and also INACCURACY: All Lists are queried at every connection after RCPT TO: ACCURACY (Graphic scale from 0 to 100% - Displayed in green): Every mail send to a spamtrap is counted as ACCURATE for those blocklists that report the IP / domain as listed. INACCURACY (Graphic scale from 0 to 1% - Displayed in red): Every mail send from an automatic or manual whitelisted sender to an existing recipient is counted as INACCURATE for those blocklists that report the IP / domain as listed. Counters for the nonexisting (virtual) zone: dnsbl-X.uceprotect.net are counted ONE only according to the description above if any of the 4 real existing dnsbl-*.uceprotect.net zones would report listed. This is because it would result in ONE acception or rejection only even if multiple UCEPROTECT-Zones would indicate listed. So the value of counter dnsbl-X.uceprotect.net reflects what would happen if all UCEPROTECT-Lists would be used together.
