As for ORBS: I have had several customers with open relays lately (which they've shut as soon as we notified them). A couple of them used our primary mail server as a smarthost, so ORBS listed it as well. In each case, ORBS failed to notify us of the listing at all. We only found out when our customers had mail blocked at servers using ORBS.
I got notified when ORBS found one of the servers under my care to be open. Ah. Here's the copy of the notification that I got. They send to postmaster@Second.Level.Domain and postmaster () Hostname Of The Mail.Server. That.Is.Found.To.Be.Open[0]. Question is, is someone answering postmaster () Your Customers Domains And Your Own.Domains? [0] My particular problem was with auth2.acclink.com. The notification went to postmaster () acclink com and postmaster () auth2 acclink com. I believe ORBS uses rDNS to get the hostname of the mail server, but you'd have to ask Alan Brown to be sure. -- North Shore Technologies, Cleveland, OH http://NorthShoreTechnologies.net Steve Sobol, BOFH - President, Chief Website Architect and Janitor Linux Instructor, PC/LAN Program, Natl.
