exim4 未通过 LMTP 将消息传递给 mailman

我正在尝试设置mailman3使用exim4来运行我的电子邮件列表。如果我尝试向我的其中一个列表发送电子邮件，则该电子邮件将被传送到实例，然后实例会不断尝试将电子邮件一遍又一遍地传送给自己，直到最终中止该过程，因为它检测到它处于循环中。据我在日志中看到的那样，exim4它从未尝试将电子邮件传送到。mailman-core

我尝试按照以下方式设置一切文档用于将 MTA 连接到邮递员。

我的整个设置正在使用docker，所以我使用 mailmanDocker 镜像和文档。内部网络运行良好，所以这应该不是问题。我能想到的唯一问题是 exim 没有正确加载配置，但我不知道如何检查，只能向它发送电子邮件并观察发生了什么（到目前为止，他们只是陷入了邮件循环）。

docker-compose.yml以下是我的文件中的相关部分：

  pg:
    image: postgres:11-alpine
    volumes:
      - db-data:/var/lib/postgresql/data
    networks:
      - backend
    environment:

      POSTGRES_USER: "${PG_USER}"
      POSTGRES_PASSWORD: "${PG_PASS}"

  mailman-core:

  exim:
    build: ./exim
    networks:
      - backend
    volumes:
      # exim4 needs access to the mailman binaries apparently

    ports:

以下是 exim Dockerfile（基于tianon/exim4：

FROM tianon/exim4

COPY 25_mm3_macros /etc/exim4/conf.d/main/25_mm3_macros
COPY 455_mm3_router /etc/exim4/conf.d/router/455_mm3_router
COPY 55_mm3_transport /etc/exim4/conf.d/transport/55_mm3_transport

exim 配置文件如下（我已经检查过它们的存在）：

25_mm3_macros：

# Colon-separated list of domains served by mailman
domainlist mm3_domains=lists.example.com

# the LMTP host is the mailman instance running at mailman-core
# for the config of this, see mailman-core/mailman.cfg
MM3_LMTP_HOST=mailman-core
MM3_LMTP_PORT=8024

# exim needs access to mailman-core data, which we have mounted
# at /opt/mailman/core. This is configured in docker-compose.yml.
MM3_HOME=/opt/mailman/core/var

################################################################
# The configuration below is boilerplate:
# you should not need to change it.

# The path to the list receipt (used as the required file when
# matching list addresses)
MM3_LISTCHK=MM3_HOME/lists/${local_part}.${domain}

455_mm3_router：

mailman3_router:
  driver = accept
  domains = +mm3_domains
  require_files = MM3_LISTCHK
  local_part_suffix_optional
  local_part_suffix = -admin : \

     -join      : -leave     : \
     -owner     : -request   : \
     -subscribe : -unsubscribe
  transport = mailman3_transport

55_mm3_transport：

mailman3_transport:
  debug_print = "Email for mailman"
  driver = smtp
  protocol = lmtp
  allow_localhost
  hosts = MM3_LMTP_HOST
  port = MM3_LMTP_PORT
  rcpt_include_affixes = true
