所以我有以下设置
安装了 postfix 的 Ubuntu 16.04 服务器，运行 BigBlueButton
在上面，我有一个带有 Greenlight 的 docker 容器，它基本上是 BigBlueButton 的前端
这个 Docker 容器的 IP 为 172.18.0.3（我在 postfix 配置文件中将其添加到我的网络中）
当我跑步时
docker run --rm --env-file .env bigbluebutton/greenlight:v2 bundle exec rake conf:check
为了检查配置和邮件是否正常工作，我得到以下输出：
Checking environment: Passed
Checking Connection: Passed
Checking Secret: Passed
Checking SMTP connection: Failed
Error connecting to SMTP - 454 4.7.1 <[email protected]>: Relay access denied
我的 Greenlight（Docker）SMTP 配置在 .env 文件中：
SMTP_SERVER=mydomain.example.com
SMTP_PORT=25
SMTP_DOMAIN=mydomain.example.com
#SMTP_USERNAME=
#SMTP_PASSWORD=
#SMTP_AUTH=
SMTP_STARTTLS_AUTO=true
# Specify the email address that all mail is sent from
[email protected]
# Specify the recipient for test emails (needed for providers like Microsoft, who are very
# strict about RFC 2606)
[email protected]
我的 postfix main.cf 文件：
# 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 $mail_name (Ubuntu)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h
readme_directory = /usr/share/doc/postfix
# TLS parameters
smtpd_tls_cert_file=/etc/letsencrypt/live/mydomain.example.com/fullchain.pem
smtpd_tls_key_file=/etc/letsencrypt/live/mydomain.example.com/privkey.pem
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${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.
mydomain = mydomain.example.com
smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
myhostname = mydomain.example.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = mydomain.example.com, localhost.example.com, localhost, localhost.localdomain, $mydomain, $myhostname
relayhost =
mynetworks = localhost, 127.0.0.1, 172.18.0.2, 172.18.0.3
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all
virtual_mailbox_domains=mydomain.example.com
relay_domains = $mydestination
html_directory = /usr/share/doc/postfix/html
我尝试对 mynetworks 设置进行各种更改，包括将其设置为 0.0.0.0，据我所知，这应该允许任何人发送邮件 - 但它仍然不起作用。
编辑：
这是我的 Postfix 日志：
connect from unknown[172.17.0.2]

答案1
您确定 IP 地址正确吗？根据您的 postfix 日志，发件人是 172.17.0.2，而不是 172.18.0.3。
您能否添加 172.17.0.2mynetworks并再试一次？
