Update templates/10-mail.conf.j2 to explicitly define standard mailboxes (Drafts, Junk, Trash, Sent) within the inbox namespace.
This change ensures that:
- These folders are automatically subscribed (`auto = subscribe`).
- They are correctly flagged with `special_use` attributes, improving compatibility with IMAP clients.
- "Sent Messages" is also recognized as a Sent folder for broader client support.
Update the Dovecot authentication template to use `%n` (user part only)
instead of `%u` (full username) in both the `passdb` username format and
the `userdb` home directory path.
This ensures that user lookups and home directory generation rely specifically
on the username portion, excluding the domain part.
- 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.
Update the `unix_listener auth-userdb` configuration in `templates/10-master.conf.j2`. This change switches the socket ownership from `vmail` to the `postfix` user and explicitly sets the group to `postfix`.
This ensures that the Postfix service has the necessary permissions to access the Dovecot authentication socket for user lookups.
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.
