Hi all,

Currently I have a mimedefang-filter in place to prevent forged From: headers 
from entering our email system. See snippet:

if (is_local_sender()) {
  adduselessdisclaimer()
} else {
  if ($Sender =~ /[EMAIL PROTECTED]/ or $Sender =~ /[EMAIL PROTECTED]/ {
    return action_discard();
  }
}

This doesn't stop emails with double From: headers from forging internal 
emailaddresses. Does anyone know of a method to stop this from happening. 
Currently I'm preventing this with a custom spamassassin rule, but I like to 
log this with MD.

Thanks, Johan
