Or does reject_unlisted_recipient get disabled completely when smtpd_reject_unlisted_recipient=no? You can then use "reject_unlisted_recipient" explicitly at the appropriate stage in the recipient restrictions. Okay, I understand why doing any of this in DATA is bad and I should have realize

Re: 'queue file write error' in only very specific instances

So those log snippets are from the logs on 50.75.172.140 (my postfix server). What more might I be looking for? On Wed, 1 Feb 2023, Wietse Venema wrote: post...@fongaboo.com: Jan 31 20:06:15 h6lix postfix/smtp[6552]: 7128C4089C: to=, relay=50.75.172.140[50.75.172.140]:25, delay=2.5, delay

'queue file write error' in only very specific instances

First off does "queue file write error (in reply to end of DATA command))" indicate a write error on my server, or on the receiver's server? Best I can tell from grepping the logs, this is happening only with two addresses: Feb 1 07:36:36 h6lix postfix/smtp[22140]: 8F6544089C: to=, orig_t

Re: how does postfix determine hostnames in 'received' header?

viktor, thank you very much for your input. it helped me to understand the issue and then solve it. since this 'special' host is the local DNS server (dnsmasq), a reverse lookup returned this weird hostname. so i had to add the DNS server to the mailhub's /etc/hosts, and the issue is solve
