This was a ridiculous miss, where on first time installation, the
well designed default e-mail template was never installed in the
DB! I never spotted this because my local dev setup, and
surprisingly, nobody ever complained that the default campaign
template was a blank slate with no styles.
Certain SMTP hosts limit the total number of messages that can be
sent within a window, for instance, X / 24 hours. The concurrency
and message rate controls can only limit that to a max of
1 messages / second, without a global cap.
This commit introduces a simple sliding window rate limit feature
that counts the number of messages sent in a specific window, and
upon reaching that limit, waits for the window to reset before
any more messages are pushed out globally across any number of
campaigns.

- Configures `max_open` and `max_idle` in default configs to `25`.
This changes the previous behaviour of connection pooling where both the
values were unset (from default config) and causes unbounded connection
limit and no connection reuse.
- Configures `db.SetConnMaxLifetime` which sets the maximum time the
connection can be reused in a pool.
- Sets `max_conn_lifetime` in default config as `5 minutes`.
Closes https://github.com/knadh/listmonk/issues/225
Lists, campaigns, and subscribers tables now support server-side
sorting from the UI. This significantly changes the internal
queries from prepared to string interpolated to support dynamic
sort params.
The link_clicks.link_id table was NULLable incorrectly. Links that
do not exist should not register a tracking entry. Fix the query
and also update the schema + migration (breaking table change).
The earlier goreleaser implementation was incorrect where every
build would trigger `make pack-release` with the list of all
cross-platform releases. Fix that to atomically run the packing
once per goreleaser build. In addition, add `make release-dry`
and `make release` for goreleaser.
A new toggle switch in Settings -> Privacy, which is off by
default, allows campaign views (pixel) and link clicks to function
without registering the subscriber ID against view and click
events, anonymising tracking. When off, the subscriber UUIDs in
view and link tracking URLs are removed, anonymising subscriber
information from HTTP logs as well.
According to [RFC6532](https://tools.ietf.org/html/rfc6532) unicode characters are supported in email address but the in-built custom regex was only validating ASCII characters.
The earlier logic for copying existing passwords from the DB to
SMTP and messenger settings when the frontend sent an empty
password was based on array positions (and flawed). This commit
introduces an internal UUID field to SMTP and Messenger settings
to keep track of password changes in the settings UI.
This is a major feature that builds upon the `Messenger` interface
that has been in listmonk since its inception (with SMTP as the only
messenger). This commit introduces a new Messenger implementation, an
HTTP "postback", that can post campaign messages as a standard JSON
payload to arbitrary HTTP servers. These servers can in turn push them
to FCM, SMS, or any or any such upstream, enabling listmonk to be a
generic campaign messenger for any type of communication, not just
e-mails.
Postback HTTP endpoints can be defined in settings and they can be
selected on campaigns.
