Postfix openDKIM设置

查询邮件MX-spf-dkim记录是否生效

postfix的dkim 需要安装opendkim

yum install opendkim -y

export domain=你的域名

mkdir /etc/opendkim/keys/$domain

cd /etc/opendkim/keys/$domain

opendkim-genkey -d $domain -s default

chown -R opendkim:opendkim /etc/opendkim/keys/$domain

echo “default._domainkey.$domain $domain:default:/etc/opendkim/keys/$domain/default.private” >> /etc/opendkim/KeyTable

echo “*@$domain default._domainkey.$domain >> /etc/opendkim/SigningTable

#编辑opendkim配置文件

vi /etc/opendkim.conf

Mode sv

KeyFile /etc/opendkim/keys/default.private  这句好像是默认的

KeyTable /etc/opendkim/KeyTable

SigningTable refile:/etc/opendkim/SigningTable

ExternalIgnoreList refile:/etc/opendkim/TrustedHosts

InternalHosts refile:/etc/opendkim/TrustedHosts

#(可选设置)如果要在邮件头信息中输出软件版本,请按如下方式更改参数。

SoftwareHeader no     yes 改为 no

 

 

 

systemctl restart opendkim

systemctl restart postfix

systemctl enable opendkim

postfix还需要添加一下参数
