Frank M. Cook asked: >>are you calling the rbl with a www dot? should be sbl-xbl.spamhaus.org.
I think you misunderstood me. In my original e-mail, I thought I made it clear that the RBL access was working just fine. The problem I was referring to was not being able to access their web site in a browser. Turns out, from other's input, it seems that SpamHaus has been having intermittent problems with their web site (or web site connectivity??) over the past couple of days. However, I am now able to access their web site. Thanks to all for the feedback. Rob McEwen
