I can off course recommend some BLs but I will do that in the other mail addressed directly to you. However... I want to leave here a comment regarding that question: Never ever just blindly trust any one to tell you what BLs to use. Never! The reason I write this is because what can be good for me can be wrong for you and vice versa. If I can recommend something regarding BLs then I recommend you to take recommendation but carefully evaluate the BLs in question and make your own decisions. At the end it is your messaging infrastructure and you should understand the impact of using BL xyz or BL abc. > > On top of that some data from dnsbl.njabl.org is already included in > > zen.spamhaus.org too.
