DNS TXT _dmarc.evert.net is “v=DMARC1; p=reject; fo=1;
rua=mailto:post(_at_)evert(_dot_)net; ruf=mailto:post(_at_)evert(_dot_)net;”,
the MLM
changed From: and no reports were generated, based on broken DMARC policy.

DNS TXT _dmarc.akamai.com contains “v=DMARC1; p=quarantine; pct=0;
rua=mailto:akamai(_at_)rua(_dot_)agari(_dot_)com, mailto:
mailauth-reports(_at_)akamai(_dot_)com;
ruf=mailto:akamai(_at_)ruf(_dot_)agari(_dot_)com; sp=none”. The MLM does not
rewrite From:. Delivering the
email to the mailing lists recipients leads to failed DMARC and a (not
aggregated) report is generated per delivered
message.
Shouldn’t ietf-smtp(_at_)ietf(_dot_)org change the From:, when for the domain
p=quarantine is set, just as for p=reject, in order
to avoid generating useless reports, and ensuring delivered emails? (Handling
“quarantine” as “reject” on the
recipients’ side is not neccesary wrong).
