Yes, I am aware of that and when the server is rebuilt in the next month or 2 the OHN will change to mail.eservicesforyou.com which will solve that. However, my concern is that Imail is waving a flag and saying I am using an internal IP address by way of this log line: 2006-05-30 01:11:05 Local7.Debug 127.0.0.1 SMTP (fe080198000003a3) [x] using source IP for mail.eservicesforyou.net [192.168.41.39] My understanding by way of the Imail KB articles is that Imail is getting that information from the registry, not from any DNS query. So my concern is that even after I rebuild the server with the OHN being mail.eservicesforyou.com the registry address value for that will be 192.168.41.39 and Imail will still announce itself with that IP in which case the problem is still there. I guess my question is if DNS was setup perfectly to where any request for resolution to the OHN returned a public IP, but the Imail registry value for address for the OHN was a private IP, would Imail still announce itself as using a private IP? I guess to test this I would send a message through my server to some one directly who would then check their SMTP log to see exactly what information was given.
