Hi, I have a system with some user accounts and is the final destination for a few domains. Some of these users forward email off the system to another system, such as yahoo or gmail. The problem I'm having is when a user is forwarding their email to an expired yahoo account, for example, and how to manage the bounces.
In particular, some mail is received from an "unattended mailbox" that doesn't accept bounces, so they sit in our queue until they expire and are purged. What is the proper way to handle this? Should I be rewriting something in the headers so it takes my system out of the loop and leaves it to yahoo and the sender to work out, or is the proper solution what I'm currently doing (leaving them until they expire)? Thanks, Alex
