Failed POP3 authentication attempt?
本文章最後由 jtain 於 2018-6-14 04:06 PM 編輯這一週來經常有USER出現這個錯誤，以至於不能收發信
Failed POP3 authentication attempt from 192.168.xx.xx for "xxx"
--> -ERR access denied
POP3 session terminated, (Bytes in/out: 47/184)
你有開啟 POP before SMTP ? 本文章最後由 jtain 於 2018-5-9 04:50 PM 編輯
有
印象中上面的錯誤是 pop3時，
如果是stmp我知道那是USER沒有先執行pop3/imap
我今天又碰到類似的錯誤，這是完整的log

解決了，最後是因為 win 2008 r2 的 ODBC 有問題
改回使用預設值，幸好mdaemon 會自動把 .mdb 轉過去，
否則我還真不知道要如何處理
