I've set up dkim-filter on my mail server. I've set up postfix to use dkim-filter as the milter; However, I'm getting the following in my logs:
Jul 7 13:00:29 magni postfix/smtpd[6742]: connect from mail-vw0-f53.google.com[209.85.212.53]
Jul 7 13:00:29 magni postfix/smtpd[6742]: D0F802BC74: client=mail-vw0-f53.google.com[209.85.212.53]
Jul 7 13:00:29 magni postfix/cleanup[6756]: D0F802BC74: message-id=<....-....mail.gmail.com>
Jul 7 13:00:34 magni dkim-filter[7039]: D0F802BC74: key retrieval failed
Why am I getting that, and how can I stop it from happening?

Since this is an inbound connection it means you have misconfigured your dkim filter it is trying to sign instead of verify the message and cannot obtain the keys.
