Presumbaly you have to DKIM or SPF or DMARC for hostname.raystedman.org,
so any way to get double-bou...@raystedman.org should help.
You have to be careful about mailer loops, though.
Postfix gives special treatmment to <> and <double-bounce@$mynostname>
to avoid an infinite loop of notifications for failed notifications.
So there waas a typo in my earlier sender_canonical_maps example,
where I used _ instead of -.
sender_canonical_maps = inline:{
{ double-bou...@mail01.raystedman.ora =
double-bou...@raystedman.org } }
Specitying a domain in the double_bounce_sender setting will not work.
The implementation does not expect @ in the double_bounce_sender
value, and should handle that.
