I use “reject_unknown_sender_domain” as one of smtpd_recipient_restrictions. What I do not understand is why only when use -o content_filter=spamassassin this turn in the mentioned error; the transaction log (in the following line @domain.eu is the SMTP server domain) is very simple:
postfix/smtpd[19810]: NOQUEUE: reject: RCPT from unknown[XXX.XXX.XXX.XXX]: 450 4.1.8 <marco.ro...@unipg.it>: Sender address rejected: Domain not found; from=<marco.ro...@unipg.it> to=<ori...@domain.eu> proto=ESMTP helo=<smtp.unipg.it> Thanks —Carlo > On 02 Sep 2015, at 11:57, Reindl Harald <h.rei...@thelounge.net> wrote: > > "NOQUEUE: reject: RCPT from unknown Sender address rejected: Domain not > found" is clearly Postfix and "reject_unknown_sender_domain" while you should > post *all* loglines for that transaction and not just one stripped line > > Am 02.09.2015 um 11:50 schrieb Carlo Manuali: >> Hi, >> >> I tried different senders and I always receive the same error.
