chkconfig postfix on postfix check

systemctl status postfix

mkdir -p /~/.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 /~/.certs

cd /~/.certs

certutil -A -n "GeoTrust SSL CA - G3" -t "Pu,Pu,Pu" -d ./ -I qq.crt

5.配置邮件发送者:

vi /etc/mail.rc

set from=408200244@qq.com

set smtp=smtps://smtp.qq.com:465

set smtp-auth-user=408200244

#

授权码

set smtp-auth-password=cnnjaqnhtohmeahg set smtp-auth=login

set ssl-verify=ignore

set nss-config-dir=/~/.certs
