OpenDKIM 忽略受信任主机文件中的主机名和域

OpenDKIM 忽略受信任主机文件中的主机名和域

根据http://opendkim.org/opendkim.conf.5.htmlExternalIgnoredHostsInternalHosts选项支持与选项相同的格式,PeerList如下所示:

该集合的每一行应包含一个主机名、域名(例如“.example.com”)、IP 地址、IPv6 地址(包括 IPv4 映射地址)或 CIDR 样式的 IP 规范(例如“192.168.1.0/24”)。

IP 地址和子网被正确识别为内部主机,但并非所有主机名和域都将被拾取。

这是/etc/opendkim.conf

127.0.0.1

localhost
mailserver                # mail server hostname

webserver.domain.local    # web server
.domain.local             # entire local domain
*.testdomain.local        # entire local test domain

以及main.cf更温和的选择:

milter_default_action = accept
milter_mail_macros = i {mail_addr} {client_addr} {client_name} {auth_type} {auth_authen}
milter_protocol = 6
smtpd_milters = local:opendkim/opendkim.sock
non_smtpd_milters = $smtpd_milters

来自的邮件192.168.100.50已按预期签名:

webserver.domain.local但尽管客户端名称已被解析,但邮件并未被识别为内部邮件:

我是否遗漏了有关如何解析主机名的信息,或者有关如何实现此功能的一些更基本的信息?我也尝试过和的域组合,*.domain.local.domain.local没有/etc/opendkim/trusted.hosts成功。

我们将非常感激所有帮助。

这个问题通过删除 中域通配符前面的星号得到解决/etc/opendkim/trusted.hosts。星号的存在不仅导致域通配符无法工作,还导致文件中所有其他字符串条目无法工作,不过 IP 地址不受影响。

IP 地址有效,但字符串无效:

127.0.0.1
::1
localhost
mailserver                # mail server hostname
192.168.100.50            # test server
webserver.domain.local    # web server
.domain.local             # entire local domain
*.testdomain.local        # entire local test domain

IP 地址和字符串均可用:

127.0.0.1
::1
localhost
mailserver                # mail server hostname
192.168.100.50            # test server
webserver.domain.local    # web server
.domain.local             # entire local domain
.testdomain.local         # entire local test domain
