Hello,
I try to run postfix, rspamd and dovecot. The 3 stars :)
Now I try to send mail to box and what happen:
Nov 18 17:12:35 netcup.silviosiefke.com postfix/smtpd[6215]: NOQUEUE: reject:
RCPT from unknown[81.91.160.182]: 450 4.7.25 Client host rejected: cannot find
your hostname, [81.91.160.182]; from=<maintenance-l-ow...@list.denic.de>
to=<lis...@silvio-siefke.de> proto=ESMTP helo=<list-2.denic.de>
This is example and this happen with Gmail and Mail.ru.
