Facts read from this source
-
Dkim signing Report an error
“DKIM (DomainKeys Identified Mail) is an email authentication method that places a digital signature (a piece of code) in the headers of your outgoing mail.”
-
Dkim automatic dns for runbox domains Report an error
“This makes it very easy to set up DKIM signing as you just need to activate it below and our systems will place the required DNS CNAME (Canonical Name) entries on our name servers for your domain.”
-
Dkim key pair creation Report an error
“Two keys are created, a private key and a public key. This is called a private/public key pair. The private key is used to sign your messages and is only available to the Runbox outgoing mail servers. The public key is published on our own dedicate DKIM DNS servers and can be seen by anyone who cares to look for it.”
-
Dkim key rotation Report an error
“In total, two sets of private/public key pairs are created but only one pair used at any time. This is for additional security and at three month intervals the keys that are used are swapped for a different new pair.”
-
Dkim cname propagation wait Report an error
“we will automatically publish the correct CNAME records for your DKIM keys and you don’t need to do anything further other than wait 10 minutes and then check to make sure everything is active by refreshing the DKIM page.”
-
Dkim selector rotation Report an error
“Selectors are just ways of identifying which of the two keys are in use, and in the signature places in the headers of your email there is some information which tells the receiving email service which selector was used so that it can look up the correct key.”
-
Dkim external dns manual setup Report an error
“If we don’t host the DNS for your domain (i.e. you registered it elsewhere and just point your MX (Mail eXchanger) record to Runbox) then you will need to place the CNAME entries in your domain’s DNS yourself.”
-
Dkim contact Report an error
“If you need any help with setting up DKIM signing, please contact support.”
-
Dkim zone file export Report an error
“The zone file format can look confusing if you are not familiar with it, but it does have the advantage that you can just copy and paste the two lines from our DKIM page that appear under the section about editing the DNS zone file”
