Hello, I have postfix-2.10.2 with milter and amavis as smtpd_proxy_filter installed. All information stored in database and at 1st min of each hour domains and recipients copied to local files. Then postmap command performed. I notice that very rarely postfix reject valid recipients. I know that [email protected] is at relayrecipients table and did not change for a long time.
Server use 40 smtpd proc and if script for example start at "Jan 27 16:01:01" then last smtpd restarting at "Jan 27 16:09:25" Jan 27 16:09:25 MYSERVER postfix/smtpd[1061]: table hash:/etc/postfix/relayrecipients(0,lock|fold_fix) has changed -- restarting Jan 27 16:08:09 MYSERVER postfix/smtpd[30332]: table hash:/etc/postfix/relayrecipients(0,lock|fold_fix) has changed -- restarting Jan 27 16:05:54 MYSERVER postfix/smtpd[1061]: NOQUEUE: reject: RCPT from zscaler.net[x.x.x.x]: 550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in relay recipient table; from=<[email protected]> to=< [email protected]> proto=ESMTP helo=<server.net> Jan 27 16:03:55 MYSERVER postfix/smtpd[3125]: table hash:/etc/postfix/relayrecipients(0,lock|fold_fix) has changed -- restarting Jan 27 16:02:10 MYSERVER postfix/smtpd[32115]: table hash:/etc/postfix/relayrecipients(0,lock|fold_fix) has changed -- restarting Jan 27 16:01:37 MYSERVER postfix/smtpd[2199]: table hash:/etc/postfix/relayrecipients(0,lock|fold_fix) has changed -- restarting At the same time between "16:01:37" - "16:09:25" a lot of mail accepted by postfix (the same domain also). My question why is this happen? What is the safe way to update recipients tables and another hash files?
