Haraka can handle thousands of connections simultaneously and deliver thousands messages per second. Haraka and its plugins are both written in asynchronous JS, and are therefore very fast. Haraka is a very good filtering MTA and has excellent spam protection (see the plugins). It also works as an MSA on port 587, with auth and Dkim_sign enabled.

Haraka comes with a built-in scalable outbound delivery engine. Mail marked for relaying (e.g. via an auth plugin), is automatically queued up for outbound delivery. Haraka's plugin-based architecture allows for an easily extensible MTA to complement traditional MTAs, which excel at managing mailboxes but lack sufficient filtering.
