I am using a Windows 2008 server and manage all our emails using MailEnable professional. We also use Magic Spam to trap most spam emails.
Unfortunately we are getting a lot of emails which are obvious spams and they have been spoofing our own emails in the "FROM" part. When I look at the message header I can see the return-path points to a completely different email address which clearly does not match the FROM part.
Is there any effective way to reject these emails using MailEnable by rejecting emails where the FROM email and return-path do not match?
Also are there legitimate cases where they will differ?
Thanks in advance
