Zitat von http://www.perlmonks.org/?node_id=345530:
| The only way to control where bounce messages go is by changing the envelope
| sender in SMTP. [...] The envelope sender can be different than From: header
| but this requires more control of the sending process.
Dies erreichst du ganz leicht mittels http://p3rl.org/Email::Sender::Manual::QuickStart#envelope_information.
