I'm running a Debian server with Courier as MTA and would like to create a mail forwarding rule that does the following:
- extract the domain from the address of the sender
- example: noreply@example.com
- forward the mail to a dynamically kind of calculated address of a catch all mailbox that has the extracted domain as prefix:
- example: example.com@mycatchallbox.com
I guess this has got be possible in some way... but how?
