DKIM public key invalid

[equynox]

Hello

I set up a domain after installing vestacp and checked also dkim support for email. Entries in dns looks ok since its been added automaticly by vesta. But when i am trying to verify i get this error message:

Public Key DNS Lookup


Building DNS Query for mail._domainkey.mydomain.com
Retrieved this publickey from DNS:
Validating Signature


result = invalid
Details: public key: not available

Can anybody help me get things right. I admit i am almost an absolute newbie in dns.

Tnx in advance for any further answer!
