CentOS配置mail.rc通过465端口发送邮件
需要先启动postfix服务 CentOS 7 启动:systemctl start postfix #1、创建目录,用来存放证书 [root@shnne ~]# mkdir -p /root/.certs/ #2、向126请求证书 [root@shnne ~]# echo -n | openssl s_client -connect smtp.126.com:465 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ~/.certs/126.crt depth=2 C = US, O = DigiCert Inc, OU = www.digicert.com, CN = DigiCert Global Root CA verify return:1 depth=1 C = US, O = DigiCert Inc, OU = www.digicert.com, CN = GeoTrust CN RSA CA G1 verify return:1 depth=0 C = CN, ST = Zhejiang, L = Hangzhou, O = "NetEase (Hangzhou) Network Co., Ltd", OU = IT Dept., CN = *.126.com verify return:1 DONE #3、添加一个证书到证书数据库中 [root@shnne ~]# certutil -A -n "GeoTrust SSL CA" -t "C,," -d ~/.certs -i ~/.certs/126.crt #4、添加一个证书到证书数据库中 [root@shnne ~]# certutil -A -n "GeoTrust Global CA" -t "C,," -d ~/.certs -i ~/.certs/126.crt #5、列出目录下证书 [root@shnne ~]# certutil -L -d /root/.certs Certificate Nickname Trust Attributes SSL,S/MIME,JAR/XPI GeoTrust SSL CA C,, #6、然后前往126邮箱打开smtp并获取客户端授权码 网页正上方:设置→POP3/SMTP/IMAP 网页左侧:客户端授权密码 #7、最后配置/etc/mail.rc,结尾添加如下内容: set smtp=smtps://smtp.126.com:465 set smtp-auth=login set smtp-auth-user=shnne set smtp-auth-password=password客户端授权密码 set ssl-verify=ignore set nss-config-dir=/root/.certs #set nss-config-dir=/etc/pki/nssdb (如果没有上面这条,就用此条) set from=shnne@126.com #7、现在发送测试邮件 看起来已经成功了,但是发送完邮件还有报错:证书不被信任,且命令行就此卡住,直接敲回车重新进入命令提示符 [root@shnne ~]# echo "content test mail" | mail -s "subject test" postmaster@shnne.com [root@shnne ~]# Error in certificate: Peer's certificate issuer is not recognized. [root@shnne ~]# cd /root/.certs/ [root@shnne .certs]# ll total 80 -rw-r--r-- 1 root root 2419 Jan 20 15:48 126.crt -rw------- 1 root root 65536 Jan 20 15:50 cert8.db -rw------- 1 root root 16384 Jan 20 15:50 key3.db -rw------- 1 root root 16384 Jan 20 15:49 secmod.db [root@shnne .certs]# certutil -A -n "GeoTrust SSL CA - G3" -t "Pu,Pu,Pu" -d ./ -i 126.crt Notice: Trust flag u is set automatically if the private key is present. 再次测试问题解决
