Basic questions:
1) Does Postfix log n...@arrl.net as the envelope sender?
<date> <time> host postfix/qmgr[pid]: queueid: from=<???>,
size=nnn, nrcpt=nnn (queue active)
2) Are there any settings that OVERRIDE sender_dependent_relayhost_maps?
As documented, sender_dependent_relayhost_maps is overruled with
relay_transport, sender_dependent_default_transport_maps,
default_transport and with the transport(5) table.
