Symptoms

電子郵件設定測試電子郵件失敗，指出正在驗證簡單郵件傳輸協定 （SMTP） 的詳細資訊。

Error
104: Sending the test email failed. Socket error : mailserver.mydomain.com
Verify the SMTP details and try again.

PowerProtect Data Manager 包含 /usr/local/brs/bin/smtp_send.py 腳本，以幫助解決 SMTP 相關問題。指令檔無法執行，並產生下列資訊：

admin@my-ppdm:~> /usr/local/brs/bin/smtp_send.py -HOST mailserver.mydomain.com -FROM test_email_address@dell.com -PORT 25 -ARGS True -S "PowerProtect Data Manager test email" -C plain -R test_email_address@dell.com
Traceback (most recent call last):
  File "/usr/local/brs/bin/smtp_send.py", line 338, in <module>
    main()
  File "/usr/local/brs/bin/smtp_send.py", line 308, in main
    outer.attach(MIMEText(args.body, args.content_type))
  File "/usr/lib64/python3.4/email/mime/text.py", line 33, in {}init{}
    _text.encode('us-ascii')
AttributeError: 'NoneType' object has no attribute 'encode'

Cause

可使用 smtp_send.py 說明顯示所有命令都是可選的，但其中大多數是必需的：

admin@my-ppdm:~> /usr/local/brs/bin/smtp_send.py -h

usage: smtp_send.py [-h] [-HOST MAILSERVER] [-PORT PORT] [-USER USERNAME]
                    [-PASS PASSWORD] [-FROM MAILFROM] [-ARGS USEARGS]
                    [-R RECIPIENTS [RECIPIENTS ...]] [-S SUBJECT]
                    [-C CONTENT_TYPE]
                    [-T {MAIL_BODY_AS_ARGUMENT,MAIL_BODY_AS_ATTACHMENT,MAIL_BODY_FROM_FILE}]
                    [-p TIMEOUT] [--hide] [-F FILENAME | -B BODY]

  -C CONTENT_TYPE       Content Type
  -T {MAIL_BODY_AS_ARGUMENT,MAIL_BODY_AS_ATTACHMENT,MAIL_BODY_FROM_FILE}
                        Message type
  -p TIMEOUT            Timeout in minutes
  --hide                hide to field from recipients
  -F FILENAME, --Files FILENAME
                        File to be attached
  -B BODY, --Body BODY  Message body

Resolution

使用時，必須使用參考的所有選項 smtp_send.py 文稿，而不是依賴於 "help" 命令輸出。語法與輸出範例：

admin@my-ppdm:~> /usr/local/brs/bin/smtp_send.py -HOST mailserver.mydomain.com -FROM test_email_address@dell.com -PORT 25 -ARGS True -T MAIL_BODY_AS_ARGUMENT -S "PowerProtect Data Manager test email" -B "This is a test email from a PowerProtect Data Manager appliance" -C plain -R test_email_address@dell.com
