Hi Last days I've been using RDNS and RBL (sbl-xbl.spamhaus.org) ckecks and many of my customers had problems. Some because they couldn't receive e-mail from other ISPs that didn't configure RDNS and others because they couldn't receive mail from blacklisted IPs.
I'm having RDNS problems even with important companies here in Spain and it's dificult to explain my customers that this is caused by other's bad configuration. My customers say: "Yesterday I could recive from XXXX and now I can't. What did you changed?". And some of these important companies say they can't set a RDNS record since they host several services per IP. I write to ask you about your experience with RDNS and RBLs. What configuration do you use? What RBL servers do you use?
