我有一个小问题。 有些垃圾邮件发送者正在从我的地址发送邮件给我。
这里是邮件标题：
From - Fri Aug 20 08:06:15 2010 X-Account-Key: account7 X-UIDL: 1201266183.2446 X-Mozilla-Status: 0001 X-Mozilla-Status2: 00000000 X-Mozilla-Keys: Return-Path: <[email protected]> Received: from mnl-latvia.lv ([unix socket]) by localhost (Cyrus v2.2.13-Debian-2.2.13-10) with LMTPA; Fri, 20 Aug 2010 07:17:26 +0300 X-Sieve: CMU Sieve 2.2 X-Greylist: delayed 328 seconds by postgrey-1.27 at mnl-bck; Fri, 20 Aug 2010 07:17:20 EEST Received: from 59.93.217.133 (unknown [59.93.217.133]) by mnl-latvia.lv (ESMTP daemon) with ESMTP id 0F8572E6970 for <[email protected]>; Fri, 20 Aug 2010 07:17:19 +0300 (EEST) Received: (qmail 2323 by uid 603); Fri, 20 Aug 2010 08:11:00 +0400 Message-Id: <[email protected]> From: [email protected] To: [email protected] Subject: [email protected] VIAGRA X Official Seller -77% MIME-Version: 1.0 Content-Type: text/html; charset="ISO-8859-1" Content-Transfer-Encoding: 7bit Date: Fri, 20 Aug 2010 07:17:19 +0300 (EEST) X-mnl-latvia.lv-MailScanner: Found to be clean X-mnl-latvia.lv-MailScanner-From: [email protected] X-mnl-latvia.lv-MailScanner-To: [email protected] 邮件服务器运行在postfix，spamassasin上。 spamassasin定义所有来自拉脱维亚networking的消息都被列入白名单。
spamassasin spam.whitelist.rules
From: *@*.lv yes
main.cf
smtpd_recipient_restrictions = hash:/etc/postfix/access, permit_sasl_authenticated, permit_tls_clientcerts, permit_mynetworks, check_policy_service inet:127.0.0.1:60000 reject_invalid_hostname, reject_non_fqdn_sender, reject_unknown_sender_domain, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_unauth_destination, permit
问题是：如果From和To相同，并且如果发件人未通过身份validation，是否可以将邮件放在smtp级别？
在邮件标题发件人是：
收到：59.93.217.133（未知[59.93.217.133]）
所以它不authentication。 我是对的 ？
在Postfix中configurationSPF并使用一些spf检查框架（tumgreyspf，postfix-policyd-spf-perl，…）。
