如果我在端口25的局域网连接到我的邮件服务器，它提供了STARTTLS
telnet mailserver.com 25 Trying 192.168.0.x... Connected to mailserver.com Escape character is '^]'. 220 mailserver.com ESMTP Postfix ehlo bla 250-mailserver.com 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN 如果我从外部尝试，我不会得到STARTTLS报价：
telnet mailserver.com 25 Trying xx.xxx.xxx.xx... Connected to mailserver.com Escape character is '^]'. 220 mailserver.com ESMTP Postfix ehlo bla 250-mailserver.com 250-SIZE 10240000 250-VRFY 250 DSN
奇怪的是，通过提交（587）端口从外部正常工作。
我的postconf -n

和我的master.cf：
smtp inet n - n - - smtpd #smtp inet n - n - 1 postscreen #smtpd pass - - n - - smtpd #dnsblog unix - - n - 0 dnsblog #tlsproxy unix - - n - 0 tlsproxy submission inet n - n - - smtpd -o smtpd_tls_security_level=encrypt -o smtpd_sasl_auth_enable=yes smtps inet n - n - - smtpd -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes
所以看起来，端口25上的STARTTLS只提供给内部IP地址，而端口587上的STARTTLS也提供给外部IP地址。 我的目标是允许在端口25上的STARTTLS用于外部IP。 我的错误在哪里？
非常感谢你提前干杯
