我已經更改了Postfix的預設FROM位址，從[電子郵件受保護]到[電子郵件受保護]
我可以很好地發送電子郵件，但是當我檢查郵件日誌檔案時，我會看到一些“未找到“錯誤。
/etc/郵件日誌：

/etc/postfix/main.cf
smtp_generic_maps = hash:/etc/postfix/generic
/etc/postfix/通用
root [email protected]
所以一切正常，但還是有這些錯誤。為什麼郵件日誌先說“未找到”，然後再幾行又說已找到？
答案1
似乎這些maps_find行是來自設定到您的/etc/postfix/generic.您的映射程序終止於
maps_find: smtp_generic_maps: hash:/etc/postfix/generic(0,lock|fold_fix): root
上面寫著這封電子郵件將發送給 root
檢查debug_peer_list並debug_peer_level進入您的main.cf以禁用此選項（我個人將其註釋掉並解決了我的日誌過於冗長的問題）。您可以找到更多文檔這裡關於這些選項
