Internal Mail-Forwarding Only
Protect your server
Large numbers of forwarded emails could get your server blacklisted. With this extension, you can disable external mail forwarding for all your customers.
Protect your customers
Customers may be tempted to forward mails from all their domains to one single address for convenience. But replying from a different, or worse, free email address (Gmail, Hotmail, etc.) is unprofessional, harms their reputation, and may get their emails caught up in spam filters or marked as ‘Promotions’.
In cases where a different email domain might be necessary, admins have the ability to switch the domain-part of email address, and the customer can change the prefix to suit their needs.
