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 (SPAM HIT - Displayed in green): Every mail send to a spamtrap or is reported as spam by an UCEPROTECT Software user is counted as ACCURATE for those blocklists that report the IP / domain as listed. INACCURACY (HAM HIT - Displayed in red): Every mail send from an automatic or manual whitelisted sender to an existing recipient or an expected mail reported by an UCEPROTECT Software user 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 3 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.
