linux使用mail以及使用java发送邮件
目录
1.安装
2.配置
3.使用
4.使用java发送邮件
1.安装
yum -y install mailx sendmail
2.配置
#未加密的发送方式通过25端口,会被公有云封掉.
cat >>/etc/mail.rc <<EOF
set from=xxx@163.com
set smtp=smtp.163.com
set smtp-auth-user=xxx@163.com
set smtp-auth-password=授权码
set smtp-auth=login
EOF#加密的方式465端口
cat >>/etc/mail.rc <<EOF
set nss-config-dir=/etc/pki/nssdb/ #加密方式配置
set smtp-user-starttls #加密方式配置
set ssl-verify=ignore #加密方式配置
set from=xxx@163.com #配置发件人
set smtp=smtps://smtp.163.com:465 #配置使用qq邮箱发送邮件，不加密方式参考上面
set smtp-auth-user=xxx@163.com #邮箱名
set smtp-auth-password=授权码 #授权码
set smtp-auth=login #认证形式
EOF
3.使用
mail -s xxx@163.com yyy@163.com </etc/hosts
xxx@163.com是发送方
yyy@163.com是接收方
4.使用java发送邮件
