我已经安装了 spamassassin 3.4.0 以供使用邮件::SpamAssassin::插件::ASN. cpan 确认已安装，dig 确认我可以从中获取 ASN TXT 记录http://routeviews.org。我的local.cf有此部分：
##### Autonomous System Plugin
# https://spamassassin.apache.org/full/3.4.x/doc/Mail_SpamAssassin_Plugin_ASN.html
ifplugin Mail::SpamAssassin::Plugin::ASN
asn_lookup asn.routeviews.org _ASN_ _ASNCIDR_
asn_prefix "AS"
add_header all ASN _ASN_ _ASNCIDR_
endif
然而，每当我查看消息中的标题时，ASN 部分都是空白的：

此外，运行spamassassing -t -D < /path/to/spam.message显示 ASN 插件正在“获取”正确的数据。但是，不知何故，标题没有被写入。有人能帮我确定如何让它工作吗？
答案1
我自己也遇到过这种情况，既然没有答案，我想我会做出回应。答案实际上是你通过同一个邮件服务器向自己发送邮件，这通常是任何人测试邮件服务器配置更改时所做的第一件事。
据我所知，您列表中的受信任网络中的任何内容都不会被视为 SpamAssassin 的中继，因此模块无法获取该中继的 ASN。外部中继连接时，您会获得 ASN 数据。
