I'm trying to diagnose why emails I'm sending out from my server's IIS SMTP Pickup Folder are getting bounced back occasionally.
One tech from a receiving company who couldn't receive the emails said:
The email would go through if you could configure your server to use
<servername>.<domain>.<tld> instead of just <servername>
I navigated to the following place in IIS:
- Internet Information Services
- myservername (local computer)
- Default SMTP Virtual Server
- Domains
- Default SMTP Virtual Server
- myservername (local computer)
Once there, I see I can rename the Domain Name to be anything I want. I've done that, but now I'm trying to figure out if it is enough.
Once I send out a test email, here is the antispam report I see from gmail, for example:
X-Forefront-Antispam-Report:
CIP:<server ip>;
KIP:(null);
UIP:(null);
IPVD:NLI;
H:<server name>;
RD:<server name>.<domain>.<tld>;
EFVD:NLI
I'm trying to figure out what any of this means, so I know if I've configured it properly. What's the difference between H
and RD
? Is there some sort of ForeFront Antispam documentation that describes what the different codes mean?
