I do not consider it a flame, but I was annoyed at the implied point of your post, "if you use DNSBLs, you are blocking real mail." That is simply not so. > Here is where I am at: I had about 10 of RBLs at one time (including > some of the ones you mentioned), but I slowly removed them.

Can they they be weighted somehow? I do not whitelist in general. I have in the past, but not at this time. I do use DNSWL.org whitelisting, but I do not think it makes any difference in what gets through. (I have not searched recently, but in the past I have found that nothing in DNSWL.org was also in Zen or BRBL.) As mentioned in part of my message that was trimmed from the quotes, I'm using postscreen, which does indeed have a scoring system. But either Zen or BRBL alone is enough evidence that it's spam. Perhaps you need to focus on the ACTUAL problem. What non-spam were you blocking? Bring those up here on the list, including logs of it being blocked, and we can find a solution. -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
