I check log for last month (30 days), i found 52 rejected messages due SPF fail, only one has valid reverse DNS and only 12 of them was trough TLS. Some IP was duplicated (44 unique). All of them are on some RBL (except one) and most of them is on more than 4 RBLs (including multiple results in composite RBLs), thus most of them will be anyway rejected later due RBLs scoring. After i switch SPF to rspamd i got only one SPF fail, which was rejected later due too many RBLs. This doesn't seem as a lot nor as legitimate mails (perhaps because my users do not use forwarders, they are not very popular in our country)... regards -- Slavko http://slavino.sk
