Postfixがポート465（SMTPS）で応答していません
Postfixがあり、ポート465でSMTPSをリッスンするように構成しました。
ポート465にTelnetで接続すると、応答しませんが、ポート25で応答します。何日もグーグルで検索しましたが、今のところ何も機能していません。だから今私はいくつかの助けを求めて来ています。以下は、Postfix用のmain.cfファイルとmaster.cfファイルです。

ポート465でSMTPS接続に応答するようにPostfixを取得するための支援をいただければ幸いです！
私はあなたにいくつかのアイデア、試すべきことを与えるために最善を尽くします...
おそらく、サービス名ではなく数値でポートを参照すると役立ちます
から 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.
したがって、このようなセクションを作成します
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
この行をPostfixサーバーに追加して、何が起こるかを確認しました。すべてのオプションなしで試しましたか？
smtps inet n - y - - smtpd
Postfixが実際にリッスンしているポートをlsofで確認できます（urdは465で定義されているポート/etc/servicesです）
$ 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)
このオプションをチェックアウトしてください。接続が拒否される原因になっている可能性があります。
-o smtpd_client_restrictions
から http://www.postfix.org/postconf.5.html
smtpd_client_restrictions（デフォルト：空）PostfixSMTPサーバーがクライアント接続要求のコンテキストで適用するオプションの制限。評価のコンテキストと時間の説明については、SMTPD_ACCESS_READMEのセクション「SMTPアクセス制限リストの遅延評価」を参照してください。
デフォルトでは、すべての接続要求を許可します。
制限のリストをコンマや空白で区切って指定します。次の行を空白で開始して、長い行を続けます。制限は、指定された順序で適用されます。一致する最初の制限が勝ちます。
これが役に立たない場合は、起動時からPostfixログを投稿してください。
