OpenDKIM 忽略受信任主機檔案中的主機名稱和網域

OpenDKIM 忽略受信任主機檔案中的主機名稱和網域

根據http://opendkim.org/opendkim.conf.5.html，ExternalIgnoredHosts和InternalHosts選項支援與選項相同的格式，PeerList如下：

該集應在每行包含主機名稱、網域名稱（例如「.example.com」）、IP 位址、IPv6 位址（包括 IPv4 映射位址）或 CIDR 樣式 IP 規格（例如「192.168.1.0/ 24 英吋）。

IP 位址和子網路被正確識別為內部主機，但未選取所有主機名稱和網域。

這是/etc/opendkim.conf

和/etc/opendkim/trusted.hosts

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

和main.cf米爾特選項：

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

來自的郵件192.168.100.50按預期簽名：

mailserver postfix/qmgr[5406]: 59CA920E11: removed

但是，儘管解析了客戶的名稱，但來自的郵件webserver.domain.local並未被視為內部郵件：

mailserver postfix/qmgr[5821]: 4F00620E11: removed

我是否遺漏了與主機名稱如何解析相關的內容，或者與此功能如何實現相關的更基本的內容？我還嘗試過*.domain.local和.domain.localin的域組合，/etc/opendkim/trusted.hosts但沒有成功。

任何和所有的幫助將不勝感激。

答案1

透過從/etc/opendkim/trusted.hosts.那裡的星號不僅阻止了域通配符的工作，而且還阻止了檔案中所有其他字串條目的工作，儘管 IP 位址不受影響。

IP 位址有效，但字串無效：

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 位址和字串都有效：

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
