助教您好,我在測試sender rewrite及DKIM Signing的時候,遇到了judge無法收到信件的狀況。根據/var/mail/ta的內容觀察到信件卡在mailServer這端,並且把信寄回mail server(status=bounce)。
除此之外,我觀察到信被dmarc policy阻擋,但我沒有安裝任何的相關app(opendmarc)。同時已經通過別的機器登入mailServer,模仿judge測試方式確認信件有被完整收到,包含dkim驗證也通過,而且也確定greylist以及spoofing都是通過judge測試的。不知道問題出在什麼地方,想請問這個問題可能會因為什麼程序導致。(圖1圖2是ta mailbox的訊息,圖3是judge check dkim的訊息,圖4是/var/log/mail.log有關bounce的資訊)
Best regard,
郭浩雲

同學好:
你的伺服器應尚未正確設定 DKIM,因此遭退回導致 Judge 顯示沒收到信。
「除此之外,我觀察到信被dmarc policy阻擋」請同學補充更多資訊,例如是在收件還是寄出時遇到的狀況?如何確定是被 dmarc policy 阻擋?

助教您好。根據下圖我得到 信被dmarc policy阻擋 的訊息。然後我是在寄出的時候遇到狀況,根據mail的訊息我不應該在server端收到測試dkim的信,因遭受阻擋,造成信沒有成功被寄出,下圖可以發現status=bounce。
謝謝助教撥冗回覆
