echo -n | openssl s_client -connect smtp.qq.com:465 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ~/.certs/qq.crt
certutil -A -n "GeoTrust SSL CA" -t "C,," -d ~/.certs -i ~/.certs/qq.crt
certutil -A -n "GeoTrust Global CA" -t "C,," -d ~/.certs -i ~/.certs/qq.crt
certutil -L -d /root/.certs

信任证书
cd ~/.certs
certutil -A -n "GeoTrust SSL CA - G3" -t "Pu,Pu,Pu" -d ./ -i qq.crt

配置/etc/mail.rc
vi /etc/mail.rc

修改值
set smtp="smtps://smtp.qq.com:465"
set smtp-auth=login
set smtp-auth-user="shuaiwang314@qq.com"
set smtp-auth-password="xxxxxxxxxxxxxxx"
set ssl-verify=ignore
