当我扫描我的DNS记录时,找到了我的DKIM记录,但是当我发送电子邮件时,没有找到DKIM签名。以下是我认为帮助解决此问题所需的初步信息。任何帮助将不胜感激。

注册商\名称服务员:Godaddy 主持:Digitalocean 操作系统:Ubuntu 14.04

DNS记录(DKIM测试网站找到域密钥并指出没有错误):

TXT default._domainkey  v=DKIM1; g=*; k=rsa; p=domainkeygoeshere    600 seconds

邮件:

echo "just a new test" | mail -s "email contents" to@destination.com -aFrom:from@mydomain.com

答复:

DKIM Information:
DKIM Signature
This message does not contain a DKIM Signature
dkim=none header.d=mydomain.com; x-hmca=none header.id=from@mydomain.com

==========================================================
Summary of Results
==========================================================
SPF check:          pass
DomainKeys check:   neutral
DKIM check:         permerror
SpamAssassin check: ham


"permerror"
  The message could not be verified due to some error that
  is unrecoverable, such as a required header field being
  absent. A later attempt is unlikely to produce a final result.

难以使用该信息进行调试,但尝试从配置文件中删除_domainkey

我的配置:

<强> DNS-Record

TXT   mail._domainkey   v=DKIM1; h=sha256; k=rsa; p=*key*   600

<强> /etc/opendkim.conf

OversignHeaders         From
Canonicalization        relaxed/relaxed
ExternalIgnoreList      refile:/etc/opendkim/TrustedHosts
InternalHosts           refile:/etc/opendkim/TrustedHosts
KeyTable                refile:/etc/opendkim/KeyTable

<强> /etc/opendkim/KeyTable

domain.tld domain.tld:mail:/etc/opendkim/mail

<强> /etc/opendkim/SigningTable

*@domain.tld domain.tld

<强> /etc/opendkim/TrustedHosts

127.0.0.1

<强> /etc/postfix/main.cf

smtpd_milters           = inet:127.0.0.1:8891
non_smtpd_milters       = $smtpd_milters
milter_default_action   = accept

同时使用/etc/opendkim/检查ls -la目录的所有者和权限,或者只需使用以下内容重新设置:

chown -Rv opendkim:opendkim /etc/opendkim
chmod go-rwx /etc/opendkim/*

配置后你重新启动了postfix和opendkim吗?

service opendkim restart
service postfix restart

我希望这会有所帮助,你会发现什么是错的。
