About 95% of the rejections/blocked from postscreen show up as “blocked by zen.spamhaus.org” in the logs even though I have several other RBLs checked by postscreen. Almost all the ones that are not listing zen, are listing the DUL list, and the rest are listing “dnsbl.sorbs.net” (without a prefix of either spam or dul)
How does post screen decide which RBL to list in the log? Is it simply the highest scored RBL that matched (in which case it seems I only need the first two and the spam.dnsbl.sorbs.net and uceprotect lists aren’t doing anything). This is what I have: postscreen_dnsbl_sites = dul.dnsbl.sorbs.net*8 zen.spamhaus.org=127.0.0.[10..11]*6 zen.spamhaus.org=127.0.0.[4..7]*5 zen.spamhaus.org=127.0.0.3*4 zen.spamhaus.org=127.0.0.2*2 spam.dnsbl.sorbs.net*2 dnsbl-1.uceprotect.net dnsbl-2.uceprotect.net list.dnswl.org=127.0.[0..255].0*-3 list.dnswl.org=127.0.[0..255].1*-4 list.dnswl.org=127.0.[0..255].[2..255]*-6 dwl.spamhaus.org=127.0.2.[2;3]*-3 swl.spamhaus.org=127.0.2.[12;13]*-3 -- "I didn't attend the funeral, but I sent a nice letter saying I approved of it." - Mark Twain
