Updates the Postfix configuration to correctly handle virtual domains when Dovecot LMTP is enabled, moving away from local system delivery settings.
- Removes `postfix_mail_domain` from `postfix_mydestination` to prevent conflicts with virtual domain handling.
- Updates `main.cf` to set `virtual_transport`, `virtual_mailbox_domains`, and `virtual_mailbox_maps` instead of `mailbox_transport`.
- Adds a new template `virtual_mailbox_maps.j2` to authorize specific users defined in `dovecot_users`.
- Adds tasks to generate the virtual mailbox map file and run `postmap` upon changes.
Added a new task to ensure the `/var/vmail` directory exists with specific ownership and permissions.
- Sets owner and group to `vmail`
- Enforces mode `0700` for security
- Applied only when dovecot is enabled
- Add `openssl` to the list of installed packages to ensure CLI availability.
- Introduce a new task to generate user password hashes using `openssl passwd -6` on the target host instead of relying on the Jinja2 `password_hash` filter.
- Update `dovecot-users.j2` template to utilize the registered output from the new OpenSSL task.
- This ensures consistent SHA512-CRYPT hash generation independent of the controller's Python environment or hashing libraries.
This introduces functionality to manage local Dovecot users utilizing a
static `vmail` system user and a flat password file.
Key changes:
- Added `dovecot_users` configuration list to defaults.
- Implemented creation of `vmail` user and group (uid/gid 5000).
- Added logic to generate a random security token using `pwgen` to prefix
user passwords.
- Created `auth-dovecot-users.conf.ext` and `dovecot-users.j2` templates
to handle `passwd-file` authentication.
- Updated `10-auth.conf` to include the new local users configuration.
- Updated README with usage instructions and token details.
Introduces functionality to install and configure Dovecot alongside Postfix to provide IMAP/POP3 services.
Changes include:
- Added tasks to install Dovecot packages (core, imapd, pop3d, lmtpd).
- Added templates for main configuration and conf.d files (auth, master, ssl, mail).
- Defined default variables for protocols, SSL settings, and Maildir location.
- Enabled Postfix SASL and LMTP integration options.
- Added a handler to restart the Dovecot service.
- Updated README.md with the new configuration variables and usage instructions.
