Jan 29, 2020 DKIM Signing Agent for Microsoft Exchange Server This agent signs outgoing emails from your Exchange Server according to the DKIM specifications. It uses the DKIM signer implementation from the awesome MimeKit project. Generate a public-private key pair by using a tool such as ssh-keygen on Linux or PuTTYgen on Windows. For help creating key pairs, see Generate RSA keys with SSH by using PuTTYgen. Vb.net generate public and private keys. Create a DKIM TXT record. Use the following steps to create a DKIM TXT record in the Cloud Control Panel: Log in to the Cloud Control Panel.
Domain Keys Identified Mail (DKIM) helps you protect your company fromemail spamming and phishing attempts. It provides a method forvalidating a domain name identity that is associated with a messagethrough cryptographic authentication.
For a complete description of DKIM, see the link to recommended DKIM sitesin the “External resources” section at the end of this article.
Note: The method described in this article differs from the way DKIM isset up for Rackspace Hosted Email and Exchange customers. If you are aRackspace Email, Hosted Exchange, or Office 365 customer, contact theRackspace Cloud Office team for help configuring the proper DKIM, DMARC, andSPF records.
The process of setting up DKIM involves the tasks detailedin the following steps:

But if you wish to go forward here, then Microsoft has a great tutorial here which explains how to setup DKIM on an on-premises Exchange environment. In general the following steps are needed: Create your signing key. You can use the dkimcore.org site to generate a key pair. This should be used for testing purposes only, since the key pair is. Jul 12, 2019 Enable DKIM keys on all custom domains in Office 365When you configure DKIM in Office 365 you may notice that some custom domains don't have DKIM keys saved.

Choose a DKIM selector.
Generate a public-private key pair.
Publish the selector and public key by creating a DKIM TXT record.
Attach the token to each outgoing email.
What is a DKIM selector?
A selector is specified as an attribute for a DKIM signature and is recorded in the DKIM-Signature header field.
Because DKIM selectors give different DNS query names, the system uses the selector as an additional name component for validation. Under each domain name, there might be one too many unique DKIM DNS records associated with different selectors.
Selectors enable multiple keys under a domain name, which can provide separate signatory controls among departments, date ranges, or third parties acting on behalf of the domain name owner. No two services or products should use the same selector.
A selector can be anything you want, such as a word, number, or a string of letters and numbers.
For example, if you choose oct2019
for your selector, the domain name wouldbecome oct2019._domain.example.com
.
Before you begin
Before you log in to the control panel and create a DKIM record, there area couple of things that you need:
Choose a simple, user-defined text string to be your DKIM selector. Theselector is appended to the domain name to help identify the DKIM publickey. See the previous section for more information about choosing aDKIM selector.
Generate a public-private key pair by using a tool such as ssh-keygen onLinux or PuTTYgen on Windows. For help creating key pairs, seeGenerate RSA keys with SSH by using PuTTYgen.
Create a DKIM TXT record
Use the following steps to create a DKIM TXT record in the Cloud ControlPanel:
Log in to the Cloud Control Panel.
In the top navigation bar, click Select a Product > Rackspace Cloud.
Select Networking > Cloud DNS.
Click the gear icon next to the name of an existing domain andselect Add DNS Record.
In the pop-up dialog box, select TXT Record as the record type.
In the Hostname text box, enter the selector text string that you chosein Step 1, followed by the literal string
._domainkey
. For example, if youuse the default as the text string, you enterdefault._domainkey
in theHostname text box.Expand the Text box by dragging the corner, and then enter thefollowing information, pasting the public key that you generated in theprevious section after the
p=
prompt:When you finish, the TXT record looks similar to the followingexample:
Click Add Record.
