阅读本教程后，我在Postfix上安装了DKIM-Filter

我的电子邮件现在有一个DKIM签名，但仍然在SPAM文件夹中登陆。 这是标题
Received-SPF: neutral (google.com: 69.164.193.167 is neither permitted nor denied by best guess record for domain of [email protected]) client-ip=69.164.193.167; Authentication-Results: mx.google.com; spf=neutral (google.com: 69.164.193.167 is neither permitted nor denied by best guess record for domain of [email protected]) [email protected]; dkim=hardfail (test mode) [email protected] Received: from promote.a2labs.in (localhost [127.0.0.1]) by promote.a2labs.in (Postfix) with ESMTPA id 34858530E8 for <[email protected]>; Mon, 28 Feb 2011 12:23:07 +0530 (IST) DKIM-Signature: v=1; a=rsa-sha256; c=simple/simple; d=a2labs.in; s=mail; t=1298875987; bh=bo+H1VYPIHMja2u7i1lnzr4k/j4Pe8iSf79bVw94XpI=; h=To:Subject:Message-ID:Date:From:Reply-To:MIME-Version: Content-Type:Content-Transfer-Encoding; b=nhTdlnUwo0iUJ92ycQzKSRjw 5Pfya0DJcJrAc8Mr2hIv8OLpgzBCzdOMWTGqR5nuUmAzgCGYBhYAM2XZwVxo9JG/iz7 oYKysmNQnskFx0TRyW3UOkDWcfHcPnCL6Y7fGzZWinmsyjsg47k+mKZg/e8jqlwTAMO PYKkt5pBz7SM0= 另外我的mail.err文件显示
Feb 28 12:17:03 ivineet dkim-filter[32181]: 1F788530E1: no signature data Feb 28 12:18:02 ivineet dkim-filter[32181]: 432BA530E2: no signature data
如何解决它
看看“无签名数据”上面的行，是这样说的：
Jul 4 10:33:46 pa04 dkim-filter[29984]: 9A95B340F6C external host localhost.localdomain attempted to send as mydomain.com Jul 4 10:33:46 pa04 dkim-filter[29984]: 9A95B340F6C: no signature data
如果是这样，创build文件/ etc / postfix / dkim / hosts与主机谁是电子邮件签名和添加到/etc/dkim-filter.conf下面几行：
ExternalIgnoreList /etc/postfix/dkim/hosts InternalHosts /etc/postfix/dkim/hosts
dkim-filter.conf中“Domain”的值是多less？ 当说明实际的域时，我遇到了同样的问题，并且通过使用通配符来解决这个问题。
从“域mydomain.com”到“域*”，保持select器和KeyFile不变。
希望能帮助到你。
这里是答案click ：a = rsa-sha256 => a = rsa
而你没有spflogging： bind9：
mail.example.com. IN TXT "v=spf1 a mx -all"
要么
mail.example.com. IN SPF "v=spf1 a mx -all"
这意味着拒绝所有邮件没有logging来自MX条目（这样的事情）
