在服务器上，我运行docker图像和后缀smtp服务器。 smtp服务器通过本地主机访问，并没有安装在任何types的容器。
问题是我可以通过terminal发送邮件在任何容器外使用sendemail，但我不能通过terminal运行sendemail发送电子邮件在任何容器内。
后缀configuration如下：
# See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name. The Debian default # is /etc/mailname. #myorigin = /etc/mailname smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h readme_directory = no # TLS parameters smtpd_tls_cert_file=/etc/letsencrypt/live/ellak.org/fullchain.pem smtpd_tls_key_file= /etc/letsencrypt/live/ellak.org/privkey.pem smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache # See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for # information on enabling SSL in the smtp client. smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination myhostname = guest8.ellak.gr alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = mail.ellak.org, guest8.ellak.gr, localhost.ellak.gr, localhost #Virtual alias domains virtual_alias_domains = ellak.org # RELAY Options relayhost = [mail1.ellak.gr]:587 smtp_sasl_auth_enable = yes smtp_sasl_security_options = noanonymous smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_use_tls = yes smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt local_recipient_maps = proxy:unix:passwd.byname $alias_maps smtp_tls_note_starttls_offer = yes #Network Access Options mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 172.17.0.0/16 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all relay_domains = * 在我运行的容器里面：
sendemail -s 172.17.0.1:25 -f [email protected] -t [email protected] -u你好-m你好
并输出以下错误：
Nov 27 19:51:14 7e56b4e22e09 sendemail[1988]: WARNING => The recipient <[email protected]> was rejected by the mail server, error follows: Nov 27 19:51:14 7e56b4e22e09 sendemail[1988]: WARNING => Received: 454 4.7.1 <[email protected]>: Relay access denied Nov 27 19:51:14 7e56b4e22e09 sendemail[1988]: ERROR => Exiting. No recipients were accepted for delivery by the mail server.
在我得到的后缀日志是：

你有什么想法，我将如何发送邮件里面的docker集装箱？
172.18.0.5不包含在mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 172.17.0.0/16
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 172.16.0.0/12
这包括所有私有172.16子网。
