I'm running Postfix 2.11.7 on FreeBSD 10.2-RELEASE.
Just wanted to get folks' opinions/rationale/thoughts on behavior of some of the RBL's.
Specifically SORBS.NET... I first set up my server using a popular FreeBSD tutorial. SORBS.NET was included in a list of recommended RBL's in the latest incarnation of that tutorial.
But it seemed like every other day I was whitelisting servers of mainstream providers like Gmail and Facebook. They seem to be... how do I say... extremely absolutist in their protocol for blacklisting? So at the end of the day it ends up not being practically useful.
I first tried whitelisting IP blocks as I found problems, but it's been a constant game of whack-a-mole (or *un*-whack-a-mole, in this context, rather?). So I finally decided to remove their reject_rbl_client entries in main.cf.
Every issue with misidentified rejections has been due to SORBS. Have others had similar experiences or different approaches?
Thanx! FONG
