Dear mail operators,
Until now we rejected emails from [email protected]
2024-04-23.log:2024-04-23 17:48:53 194.95.238.12 <22>Apr 23
17:48:53 mgw6-erl postfix/smtpd[744016]: NOQUEUE: reject: RCPT from
fra-smtp2.oracleindustry.com[138.1.67.161]:19102: 554 5.1.8
<[email protected]>: Sender address rejected: Domain not
found; from=<[email protected]> to=<[email protected]>
proto=ESMTP helo=<fra-smtp2.oracleindustry.com>
because the return path would not work.
$ host invoices.premierinn.de
$
Additionally, [email protected] also does not work:
(connect to relay2.netnames.net[185.26.230.89]:25: Connection
timed out)
[email protected]
(No idea, if it’s some kind of greylisting. Unlikely as I sent it 80
minutes ago.)
If their operators are on here, or somebody knows them, please give them
a heads-up.
Kind regards,
Paul
PS: Of course, their software does not detect rejected messages/failed
deliveries, and their staff claims, it’s in the spam folder.
