# TODOs after running this playbook:
#
# Open the firewall:
#
# - open or DNAT the TCP ports 25, 143, 587, 4190 to the host (incoming)
# - allow outgoing traffic
#
# Configure mail DNS for your host:
# Configure mail DNS:
#
# - MX
# - PTR (IPv4 and IPv6)
#
# Add SPF, DMARC and DKIM DNS records whenever you add a mail domain:
# SPF, DMARC and DKIM DNS records should be created when adding a domain:
#
# - SPF ('IN TXT "v=spf1 mx"' or more)
# - DMARC ('_dmarc IN TXT "v=DMARC1; p=reject; rua=mailto:admin@mymaindomain.org; adkim=s; aspf=s;"')
# - SPF (IN TXT "v=spf1 mx" or more)
# - DMARC (_dmarc IN TXT "v=DMARC1; p=reject; rua=mailto:admin@mymaindomain.org; adkim=s; aspf=s;")
# - DKIM (rspamadm dkim_keygen -d mymaindomain.org -s 20190911 -b 4096;
# get the DNS entry and also save the private key)
# put the DNS entry in your zone file and save the private key
# into /var/lib/rspamd/dkim/mymaindomain.org.20190911.key
# and
# chown _rspamd /var/lib/rspamd/dkim/*
# chmod 400 /var/lib/rspamd/dkim/*
# and enable it by putting a line
# mymaindomain.org 20190911
# into /etc/rspamd/dkim_selectors.map
# followed by systemctl reload rspamd)
#
# Replace the ssl certificates with signed ones.
# Please open the firewall: open or DNAT tcp ports 25, 143, 587, 4190 to the host (incoming)
#
# Replace the dovecot ssl certificates in /etc/dovecot/private with signed ones.
#
# Users and domains can be added to the PostgreSQL tables;
# code for that is not part of this playbook.
# Mind that if you create a catchall alias, you must also
# add an alias for each account to the aliases, or you can
# prepend the following to the SELECT in /etc/postfix/aliases.cf
# SELECT u.username || '@' || d.name FROM users u JOIN domains d ON u.domain_id=d.id WHERE d.relay_transport is null AND u.username || '@' || d.name = '%s'
# UNION
#
# - put the domain name in table domains
# - create a user in table users using `doveadm pw -s PBKDF2`
# - create aliases
#
# Users should use the following parameters for IMAP and mail submission.
# Note you will need to use the server_name for which you have installed the ssl certificates.
# Or you will have to configure dovecot to use multiple certs:
# https://doc.dovecot.org/configuration_manual/dovecot_ssl_configuration/#with-client-tls-sni-server-name-indication-support
#
# IMAP:
#
# - server_name: mail.mydomain.org
# - port: 143
# - connection_security: starttls
# - auth_method: normal password
# - username: {user}@{configured_domain}
#
# Mail submission:
#
# - server_name: mail.mydomain.org

# - connection_security: starttls
# - auth_method: normal password
# - username: {user}@{configured_domain}
- name: install mail_system
