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
