Hi,
in my humble opinion:
re: incoming: you only need to configure the process that serves your incoming mail to route/forward it to the LMTP port of mailman as described in the docs, for example here: https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.ht...
in
# /etc/exim4/conf.d/transport/55_mm3_transport mailman3_transport: driver = smtp protocol = lmtp allow_localhost hosts = localhost port = MM3_LMTP_PORT rcpt_include_affixes = true
If you are in a position to set up Exim as the local MTA, you could use my ansible config:
https://github.com/rivimey/ansible-exim4
to install it very simply. Ansible is a generic tool to configure software on hosts, and this config tries to abstract a lot of the knowledge I have gained into a very simple config. For example, this is the config I use to set up as a 'smarthost', accepting and forwarding all mail:
######################### EXIM SMARTHOST
exim_server_name: "{{ hostname_fqdn }}"
exim_disable_ipv6: no
# TCP/IP ports on which exim should listen for mail. Keep things simple.
exim_listen_ports: [ 25 ]
exim_tls_ports: []
exim_local_domains: []
# These define the basic operation: here, a non-local smarthost.
exim_deliver_direct: no
exim_deliver_smarthost: yes
exim_deliver_localuser: no
# Where is the smarthost?
exim_smarthost_authenticated: no
exim_smarthost_address: post.ivimey.org
# Pi doesn't include spamd support.
exim_use_spamassassin: no
exim_use_dkim: noWhile this is a fragment of my main mailserver config, which deals with mailman, multiple email domains, TLS, DKIM, user auth, spam detection, and delivery to dovecot:
######################### EXIM
# TCP/IP ports on which exim should listen for mail
exim_listen_ports:
- 25
- 465
- 587
# Ports (in exim_listen_ports) that are TLS by default.
exim_tls_ports:
- 587
# User/password lookup on local mysql server:
exim_mysql_hostname: localhost
exim_mysql_database: mail
exim_mysql_user: post
exim_disable_ipv6: true
exim_server_name: ivimey.org
exim_intercommand_delay: 1s
exim_auth_store_mysql: yes
exim_deliver_direct: yes
exim_deliver_smarthost: no
exim_imap_transport: yes
exim_local_parts_suffix: yes
exim_use_antivirus: no
exim_use_dkim: yes
exim_use_spamassassin: yes
# see also dovecot_dir_storage
exim_virtual_homes: /opt/mail/home
# Optional parts:
exim_mailman_transport: v3
exim_mailman_transport_host: mailman.ivimey.org
exim_mailman_transport_port: 8024
exim_mailman_root: "{{ mailman3_var_dir }}/lists"
exim_procmail_transport: noFor the interested, I also have an ansible config for mailman itself, though it is not necessary to use both together:
https://github.com/rivimey/ansible-mailman3
Whether or not you use my configs, I would definitely recommend trying Ansible out as a good way to configure software in (a) a repeatable and sane way, and (b) to take advantage of the experience of those who have created the configs, so you don't make too many mistakes!
Best regards,
