I looked at yours, no Postfix involved up to liszt.debian.org.


That's because I reconfigured my MUA to send mail directly to my ISP, instead of to $HOSTNAME.

my ISP changed something (but I don't remember the error) so that
I'm no longer able to send email out to the Big Bad Internet using
Postfix as a relayhost.

Probably something like "Sender domain must exist", that's what I
get if I disable address rewriting.

Attached is the transcript of a failing smtp session with my ISP, no
need to mangle anything since that info is contained in the Received:
headers of any outgoing mail.
