I will also introduce the usage of DKIM "selector" and "sender rule". How DKIM works? When an email claims to originate from a certain domain, DKIM provides a mechanism by which the recipient system can determine that the email is authorized to be sent by that domain. The work flow is illustrated as follows: Edited by user Thursday, May 14, 2015 6:23:59 PM(UTC)  | Reason: Not specified

DKIM signature is based on the domain of sender email address, it is unrelated to the name of IIS SMTP server. You can simply input your sender domain, use default settings for other parameters, finally click "Save" to create your DKIM signature.

Now open DKIM manager and select your domain and click "Export Public Key": After the public key is exported, you should deploy it in your domain DNS server.

In this case, you cannot add DKIM signature to such email, as you don't have permission to deploy DKIM public key to sender domain DNS server. Of course if you don't send email from outside email address, or you don't need to sign DKIM for those emails, you can simply ignore this topic. You can use "Sender Rule" as follows: Edited by user Thursday, May 14, 2015 6:25:37 PM(UTC)  | Reason: Not specified

"Selectors" is arbitrary names below the "_domainkey" namespace. The most important thing is: "selector" indicates your DKIM public key location. For example: if your domain selector is: "s1024", your public key DNS record is "s1024._domainkey.yourdomain"; if your domain selector is: "mta1", your public key DNS record is "mta1._domainkey.yourdomain". If you have only one IIS SMTP server, you can ignore the following sections. Edited by user Thursday, May 14, 2015 6:25:50 PM(UTC)  | Reason: Not specified
