#can send,but cause a error that "Error in certificate: Peer‘s certificate issuer is not recognized."So change a method that don‘t know why,but it works:

mkdir /root/.certs/
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
cd .certs
certutil -A -n "GeoTrust SSL CA - G3" -t "Pu,Pu,Pu"  -d ./ -i qq.crt

vim /etc/mail.rc
set nss-config-dir=/root/.certs/

最后，好像使用crond执行定时任务时，程序里都需要使用绝对路径。
