Added in 5.0.0, the bounced email detector helps you save server load and avoid being mistaken for a spammer. It reads bounce notifications and automatically processes them for you. All emails to the deceased address are halted until the member changes their email address.

You'll need to set up your bounce collector account as a real email account. Set a disk quota of no more than 5 MB -- tens of megabytes worth of messages will cause it to choke before it can process even one. Your hosting control panel will offer a way to set up the account. Ask your web host for help if necessary.

Once you have the email address created, go to Admin Panel -> Emails -> Bounce Detector and follow the on-screen instructions.
