Hello, Like Andrew said: "exim refuse to open files with names derived from the incoming message". $sender_address_domain is derived directly from the incoming message. You need to use the result of a lookup (${lookup{$sender_address_domain}...}, perhaps with ret=key) instead. cu Andreas -- `What a good friend you are to him, Dr. Maturin.
