Hello there, I have a setup with 2 MX :
domain.tld mx 10 mx1.domain.tld domain.tld mx 30 mx3.domain.tld For some operational reason mx3 replys all mail with a 454 which is TEMPORALY error... : Jun 14 23:22:55 mx3 postfix/smtpd[83891]: NOQUEUE: reject: RCPT from mail-eopbgr50127.outbound.protection.outlook.com[40.107.5.127]: 454 4.7.1 <u...@domain.tld>: Relay access denied; from=<fabrice....@xxx.com> to=<u...@domain.tld> proto=ESMTP helo=<EUR03-VE1-obe.outbound.protection.outlook.com> It trys about 31 times.... But they didn't had the idea to check the mx1... which is ready for relay. Is there any good reason that outlook.com works like a spammer trying to send mail ONLY to lowest MX server ???? Really guys fix your stuff... Regards, Xavier _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
