Question

I have configured a new email server for my company, we are using a cloud server on theplanet.com and a shared hosnting on bluehost.com, I configured the server using iredmail, all works great but when I try to test the dkim keys with amavisd testkeys it returns:

TESTING#1: dkim._domainkey.mydomain.com   => invalid (public key: not available)

I set the dns record on dns panel in blehost

name: mail._domainkey
type: txt  
value:"v=DKIM1; p=MIGfM......" 

when I try to validate via [e-mail] it returns

DKIM check details:
----------------------------------------------------------
Result:         permerror (key "dkim._domainkey.mydomain.com" doesn't exist)

Please help me with this error

Answer 1

You created a DNS record of mail._domainkey.mydomain.com but your DKIM signer is using a selector of dkim therefore it’s looking up dkim._domainkey.mydomain.com. If you rename the DNS record so that they match up it should work.
