Postfix 未觸發 OpenDKIM milter
我一直在嘗試使用 opendkim 開始對通過 postfix 發送的郵件進行簽名。查看日誌，看起來與 postfix 進行通信的嘗試為零：

milter_protocol = 6 milter_default_action = accept smtpd_milters = unix:/opendkim/opendkim.sock internal_mail_filter_classes = bounce non_smptd_milters = unix:/opendkim/opendkim.sock我在一個類似的問題上看到這是由在 master.cf 上為後綴設置 no_filter 引起的，但對我來說並非如此。這是我的master.cf：

此外，我嘗試為 non_smtpd_milters 指定完全虛假的值，並且當我使用 sendmail 發送測試電子郵件時，日誌中沒有錯誤或任何內容！？怎麼了？
這實際上真的很尷尬…… non_smtpd_milters 指令是用錯字編寫的（如您在上面的問題中所見）：
non_smptd_milters = unix:/opendkim/opendkim.sock我寫的是 non_ smptd milters 而不是 non smtpd _milters…
向任何我可能在這件事上浪費時間的人道歉。
