Hi,

Just trying to get my head around how to do dkim verification. When 
doing the ${lookup dkim{}} are you supposed to use the domain from the 
From: header? Ie, would this be sane:


deny set acl_m1  = ${lookup dkim{${lc:${domain:$h_from:}}}}
      condition   = ${if eq{$acl_m1}{bad}}
      message     = Bad DKIM signature

I'm not asking whether or not it is sane to block an email with a bad 
signature, I'm asking whether or not that method of looking up the 
validity of a signature is correct?

On the example at http://wiki.exim.org/DKIM it says to use "${lookup 
dkim{domain.example}}" but doesn't explain what you're supposed to 
replace domain.example with.

Mike
