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.
