It is sometimes desireable to avoid autoresponding to messages that have been forwarded from one local user to another.
This is especially useful if you regularly forward mailboxes to multiple destinations and want to avoid each of those destinations from generating their own autoresponses.
This whitelist allows you to enter both email addresses (which aren’t useful here) as well as headers that will cause an autoresponder to be skipped, in this case we’re adding the X-MDRedirect header, a header MDaemon adds when a message is forwarded.
- Go to the Accounts menu
- Select “Account Settings”
- Find “Auto Responders”
- Open the “White List” submenu
- Add “X-MDRedirect: 1” to the autoresponder whitelist/exception list
