localhost weist ab und sagt:
550 5.1.1 <empfaenger at example.com>: Recipient address rejected: undeliverable address
WEIL
mx01.example.com[ip.address] sagt: 554 5.1.8 <double-bounce at mail.apis.de>: Sender address rejected: MX record not found (in reply to RCPT TO command)

offenbar macht loclahost irgendeine Adressüberprüfung, gerät damit an
mx01.example.com[ip.address], der die Address probe nicht mag

Die ist nämlich defaultmäßig:
# postconf -d |grep verify_sender
address_verify_sender = $double_bounce_sender
double_bounce_sender = double-bounce

Was dann zu double-bounce @ $myorigin wird.
