Option to not allow email forwarding to external domains
As SPF/DMARC implantation grows, users who forward emails to gmail/hotmail etc are causing server IPs to become blacklisted and also emails are bouncing. The forwarding server is not an authority to send for the original sender, and also forwarding spam is reducing the reputation of the server IP.
Users should use IMAP/POP collection , not forwarding, so we should be able to disable external forwarding. The box for forwarding should only accept email address within the local subscription domains. Easy to validate.
Thank you for your input! We will consider this functionality in upcoming releases if it will be popular.
