Hi,

I am getting an error message from some email destinations that I am trying to send an Email to.

The email bounces back with the following message:

"550-DKIM: encountered the following problem validating mydomain.com: 550 pubkey_unavailable (in reply to end of DATA command)
Return-Path: Received: from server.mydomain.com"

Can you please tell me, which key I need to place into the DNS server settings on my server.
Is it the key in "/var/lib/dkim/mydomain.com.pem"?

Or can I switch this DKIM check off?

Thanks in advance for your help,

Chris
