Postfix 臨時查找失敗
我正在嘗試設置後綴，但出現“臨時查找失敗”錯誤

編輯：我創建了一個空的 /etc/aliases，然後創建了
newaliases新問題（在 telnet 中）：rcpt to: dzervas@dzervas.gr 550 5.1.1 <dzervas@dzervas.gr>: Recipient address rejected: User unknown in local recipient table但！：
rcpt to: root@localhost 250 2.1.5 Ok data 354 End data with <CR><LF>.<CR><LF> hhahahahha . 250 2.0.0 Ok: queued as <some-code>編輯 2：
Recipient address rejected: User unknown in local recipient table通過在 main.cf 中設置解決了local_recipient_maps =然而，現在我發給 dzervas@dzervas.gr 的郵件排隊了！它沒有像它應該的那樣進入 /var/mail/vmail/dzervas.gr/dzervas/ ！
執行
newaliases。如果 /etc/aliases 不存在，則先創建它，然後執行newaliases.也可能更新/添加
alias_maps = hash:/etc/aliases到 /etc/postfix/main.cf 以消除其他警告。然後再試一次。
（如果您使用 telnet 進行測試，則不需要使用 DNS）。
第 2 期：首先從 中刪除
$myhostname, $mydomain,，mydestination因為此處不應列出虛擬域。然後添加（到 main.cf）：
virtual_mailbox_domains=dzervas.gr重新載入後綴並重試。
mynetworks 需要嚴格的網路範圍
就我而言，.ip 中的 IP 範圍有誤
/etc/postfix/main.cf。# Wrong; Temporary lookup failure mynetworks = 172.16.0.0/8 # OK mynetworks = 172.16.0.0/12
/var/log/maillog我後來注意到了一個錯誤。10 月 4 日 13:47:54 後綴/smtpd
$$ 25056 $$：警告：“172.16.0.0/8”中的非空主機地址位，也許您應該改用“172.0.0.0/8”
如果有人從Google的熱門搜尋中來到這裡
Temporary lookup failure，我會說請檢查您的$mynetworks格式。
