We use DKIM on our outbound here with MS and postfix.  We just have 2 instances of postfix running. The first one scans the email with MS and the second signs the email before it leaves our servers.

Hello All,

I've just implemented MailScanner.  Great software by the way!  When I run MailScanner I run into OpenDKIM problem.  My OpenDKIM was working already before I run the MailScanner.
Now even if OpenDKIM adds a signature, it will result o dkim: permerror (bad sig).  I know MailScanner inserts some information inside the header and probably overwrites the OpenDKIM header information?
If so, does anyone can help me solve this?

Looking forward to hearing anyone.
