Hi,
I have stopped receiving mails from openSUSE mailing lists some time late on Monday.
The issue is that the HELO hostname sent by the machine does not resolve anymore:
2023-08-22T11:15:53.721108+02:00 nuss postfix/smtpd[4123954]: NOQUEUE: reject: RCPT from proxy-nue1.opensuse.org[2001:67c:2178:8::145]: 450 4.7.1 : Helo command rejected: Host not found; from= to= proto=ESMTP helo=
DNS has this to say:
;; OPT PSEUDOSECTION:
; EDNS: version: 0, flags:; udp: 512
; EDE: 22 (No Reachable Authority): (At delegation infra.opensuse.org for anna.infra.opensuse.org/a)
;; QUESTION SECTION:
;anna.infra.opensuse.org. IN A
My guess is that something was migrated somewhere or renamed, and someone forgot to adjust the HELO hostname ;).
Cheers,
Nik
