====== CentOS7 設定 mailx 寄出 log 方式 ======
  * 安裝 mailx <code sh>
yum install mailx
</code>
  * 修改 /etc/mail.rc 參考以下設定<file>
:
:
set from=jonathan@mail.ichiayi.com
# set smtp=smtp://smtp.server.tld:port_number
set smtp=smtp://mail.ichiayi.com:587
# tell mailx that it needs to authorise
set smtp-auth=login
# set the user for SMTP
# set smtp-auth-user=user@domain.tld
set smtp-auth-user=jonathan
# set the password for authorisation
set smtp-auth-password=**mypassword**
set ssl-verify=ignore
set nss-config-dir=/etc/pki/nssdb
set smtp-use-starttls=yes

</file>
  * 驗證是否可寄出測試信 <code sh>
echo "TEST...信件內容" | mail -s "TEST Sub..信件主旨" jtsai@ichiayi.com
</code>如果成功測試結果類似以下訊息<cli>
[root@pve-rclone ~]# echo "TEST...1" | mail -s "TEST Sub..1" jtsai@ichiayi.com
[root@pve-rclone ~]# Error in certificate: Peer's certificate issuer is not recognized.
</cli>

<note>
  * 出現 Error in certificate: Peer's certificate issuer is not recognized. 是憑證無法驗證是否合法的訊息, 因為有設定 <file>set ssl-verify=ignore</file>所以信件還是可以寄出
</note>
