Second: Show logs, not altered apart the localpart. > Unfortunately, the mail gateway servers may delay while processing mail > (esp. if there is some increased load at the time, so the queue may take > longer to get processed), so such mails may delay for an unacceptable amount > of time. Please show logs. Because the e-mail you showed lists a delivery time of less then five minutes. Most of the time not related at all to Amavis. > ====================================================== Verification Mail > Example / Start =================================================== Let's go through the mail step by step. > Date: Tue, 01 Mar 2022 06:36:14 +0000 > Received: from westeurope0.notifyp.svc.ms (52.232.126.143) by > VE1EUR03FT048.mail.protection.outlook.com (10.152.19.8) with Microsoft SMTP > Server (version=TLS1_2, cipher=TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384) id > 15.20.5017.22 via Frontend Transport; Tue, 1 Mar 2022 06:36:14 +0000 So submitted 06:36:14Z. > Received: from EUR05-AM6-obe.outbound.protection.outlook.com > (mail-am6eur05on2107.outbound.protection.outlook.com [40.107.22.107]) > by mailgw1.noa.gr (NOA MAIL ICXC-NIKA) with ESMTPS id 4K76w10b2bzLrN2 > for <[email protected]>; Tue, 1 Mar 2022 08:36:16 +0200 (EET) Received two seconds later at mailgw1.noa.gr.
