Iam running Cento 5.2 perfect server with ISPConfig, with Domainkeys In Postfix Using dk-milter. Everything is running well and perfect, the emails are being signed, thanks for the howto's. I'm just wondering though, can I also implement Postfix DKIM With dkim-milter? I want to know if it is possible to implement them both and what adjustments I would need to do. Thanks in advance.
