Postfix 在埠 465 (SMTPS) 上沒有響應
我有 Postfix，我已經將它配置為在埠上
465偵聽SMTPS.當我遠端登錄到埠 465 時，它沒有響應，但它確實在埠 25 上響應。我已經搜尋了好幾天，到目前為止沒有任何東西對我有用；所以現在我來尋求幫助。下面是我用於 Postfix 的 main.cf 和 master.cf 文件。
main.cf

我會盡我所能給你一些想法，嘗試的東西……
也許以數字而不是服務名稱來指代埠會有所幫助
來自http://www.postfix.org/master.5.html
Service name The service name syntax depends on the service type as described next. Service type Specify one of the following service types: inet The service listens on a TCP/IP socket and is accessible via the network. The service name is specified as host:port, denoting the host and port on which new connections should be accepted. The host part (and colon) may be omitted. Either host or port may be given in symbolic form (host or service name) or in numeric form (IP address or port number). Host information may be enclosed inside "[]"; this form is necessary only with IPv6 addresses. Examples: a service named 127.0.0.1:smtp or ::1:smtp receives mail via the loopback interface only; and a ser- vice named 10025 accepts connections on TCP port 10025 via all interfaces configured with the inet_interfaces parameter.所以創建一個像這樣的部分
465 inet n - y - - smtpd -o syslog_name=postfix/smtps -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes -o smtpd_reject_unlisted_recipient=no -o smtpd_client_restrictions=$mua_client_restrictions -o smtpd_helo_restrictions=$mua_helo_restrictions -o smtpd_sender_restrictions=$mua_sender_restrictions -o smtpd_recipient_restrictions= -o smtpd_relay_restrictions=permit_sasl_authenticated,reject我將此行添加到我的 Postfix 伺服器以查看會發生什麼並且它起作用了。您是否嘗試過沒有所有選項？
smtps inet n - y - - smtpd您可以檢查 Postfix 實際監聽的埠
lsof（urd是465定義的埠/etc/services）$ lsof -iTCP -sTCP:LISTEN | grep master master 10387 root 12u IPv4 1303420 0t0 TCP *:smtp (LISTEN) master 10387 root 13u IPv6 1303421 0t0 TCP *:smtp (LISTEN) master 10387 root 17u IPv4 1303426 0t0 TCP *:urd (LISTEN) master 10387 root 18u IPv6 1303427 0t0 TCP *:urd (LISTEN)簽出此選項。它可能會導致連接被拒絕。
-o smtpd_client_restrictions來自http://www.postfix.org/postconf.5.html
smtpd_client_restrictions（預設值：空） Postfix SMTP 伺服器在客戶端連接請求的上下文中應用的可選限制。有關評估上下文和時間的討論，請參閱 SMTPD_ACCESS_README，“延遲評估 SMTP 訪問限制列表”部分。
預設是允許所有連接請求。
指定限制列表，以逗號和/或空格分隔。通過以空格開始下一行來繼續長行。限制按指定的順序應用；第一個匹配的限制獲勝。
如果這些都沒有幫助，請您從啟動時發布您的 Postfix 日誌嗎？
