Haraka
Haraka is capable of managing thousands of simultaneous connections and can process an impressive volume of messages each second. Both Haraka and its plugins are developed using asynchronous JavaScript, resulting in exceptional speed and performance. With robust spam protection mechanisms available through its plugins, Haraka serves effectively as a filtering MTA. Additionally, it functions well as a Mail Submission Agent (MSA) on port 587 when utilizing authentication and DKIM signing plugins. Unlike traditional mail servers such as Exchange or Postfix, Haraka is not designed to act as a mail storage solution, Local Delivery Agent (LDA), or an IMAP server like Dovecot or Courier. Instead, it is typically combined with these systems for enhanced functionality. The built-in outbound mail delivery engine of Haraka is scalable, ensuring efficient processing of messages marked for relaying through authentication plugins, which are automatically queued for delivery. Furthermore, Haraka's plugin framework allows for easy extensions, making it a complementary option for traditional MTAs that may lack adequate filtering capabilities, thus enhancing the overall email handling process. This modular approach provides flexibility, enabling users to tailor their email solutions according to specific needs.
