I did have in main.cf: unknown_address_reject_code = 550 Now I also have: reject_tempfail_action = discard Still postfix respond with a 450 to fetchmail: Jul 14 18:52:43 rap postfix/smtpd[17637]: NOQUEUE: reject: RCPT from rap.rap.dk[127.0.0.1]: 450 4.1.8 <jets...@server30.reverya.com>: Sender address rejected : Domain not found; from=<jets...@server30.reverya.com> to=<k...@localhost> proto=ESMTP helo=<rap.rap.dk> I now have 6 of such email in my IMAP folder. I noticed anther thing: another of my domain not found emails really times out. sys...@doremo.jp - And then I don't understand why this is not a SERVFAIL. This happens repededly. And acces to the .jp domain should be readily available, and then the .jp root server should be able to tell if it did have any info in the second level domain. But then .jp has sectoral domains on the 2nd level, like ac.jp and or.jo. An arbitrary abdjd.jp yields a NXDOMAIN, The query times out after 30 secs. So in my humble eyes it seems like a DNS timeout is actually a timeout on the authoriative server, and that SERVFAIL is not at timeout, and it does not reflect a timeout at the authoritative server. Consequently it should be handled by the unknown_address_reject_code statement. Hmm, also tried to do reject_tempfail_action = accept To get the mail thru, and hope that razor/spamassassin would kill them, eventually I would had to delete it by hand. But still I get the 450 response code from postfix... Any ideas on how to get rid of the 450 code, or other actions?
