Features

Sending

Send text / HTML email via the Resend REST API; multiple recipients (comma / semicolon / newline / space separated).

Rhai-driven

Identity resolution, send gating, sending and counting live in scripts/default.rhai. Reload from the Script page — no recompile needed.

Fixed From name

Configure the From name once in Settings (e.g. Soup Team <noreply@soup.dev>); every mail uses it.

Send counters & quota

• Total and current-period (cycle start, default 1st of month) counts
• Free / Pro / Scale or a custom monthly limit
• Live remaining = quota − current-period count, turns red when exhausted

Encryption

• Per-category password: libsmx SM4-GCM, encrypt API Key and From name separately
• Shared password: ciphertext stored, password never on disk
• Encrypted run logs: ui::log(...) stored as SM4-GCM ciphertext under a machine-local key

History & drafts

• Every attempt (success / failure / blocked) is written to history.sml (cap 1000)
• Drafts restore automatically on next launch

Attachment progress

Status bar shows 3.2 MB / 10.0 MB (32%) with per-second refresh; requests are time-bound (connect 15s, total scaled with attachment size up to 300s).

Automation (Rhai API)

fn my_task(args) {
    let to = args[0];
    send_mail(to, "Subject", "Body", false, "", []);
    return "ok";
}
api::register("my.task", Fn("my_task"), "My automated task");

Command line: resender run <handler> [args...] — great for cron / scheduled tasks.
