疑似異常登入,暫停 d844211@alumni.nthu.edu.tw 等 52 筆信箱帳號驗證寄信服務

主旨:查信箱帳號 d844211@alumni.nthu.edu.tw 等 52 筆信箱帳號使用 SMTPAUTH 疑似異常登入(或寄信),因此暫停該帳號使用驗證寄信服務,詳說明。

說明:

  1. 查信箱帳號 d844211@alumni.nthu.edu.tw 等 52 筆信箱帳號(清單詳後)於 2019/03/09-11 有使用 SMTPAUTH 異常登入(或寄信)現象,為防止事態擴大,已暫停該帳號使用驗證寄信服務。
  2. 此帳號係屬校友服務中心管理,已用電子郵件轉知該單位郵件系統管理人員後續處理;如該帳號欲復用驗證寄信服務,請由該單位管理人員回覆本中心處理
  3. 由於網路詐騙盛行,提醒使用者切勿將信箱密碼寄給任何人,以免帳號被盜用。此外,勿再使用相同密碼,並請提高密碼強度可降低被駭客猜中的機率
  4. 如欲進一步了解所寄出的異常信件,請參閱「如何找尋郵件記錄器中的信件?」,查詢發生當日的送件匣(外部發送或本地發送)即可。另,有少數情況僅有成功登入,但還未寄出異常信件(可能為入侵前期,日後才發信),此時郵件記錄器查無信件,故若需查閱其登入明細者,請洽 opr@net.nthu.edu.tw (來信請附本公告網址及您的 email address,以利提供資料)。如為誤判,敬請來信告知,謝謝!
