  • Has anyone setup a Linux based internal only smtp relay?
    I've had something of the same experience with Postfix, u/0x29aNull. Check out OpenSMTPD. It is lightweight and standards compliant. I know that there are packages for Debian and Alpine Linux. There may also be ones for Fedora/RHEL derivatives. I use it in my environment on OpenBSD. Source: about 1 year ago
  • DKIM Migration: Rpamd instead of DKIMproxy out on OpenBSD / OpenSMTPD
    When I installed Rspamd with on OpenBSD / OpenSMTPD the other day, DKIMProxy out (dkimproxy_out daemon), which had been got via OpenBSD Ports package system, was used to add DKIM signatures to mails in order to improve security on emails. - Source: dev.to / almost 3 years ago

  • How do you handle SMTP and service emails?
    The next time this happens I'll move to a self hosted solution, like haraka or anonaddy. Source: over 1 year ago
  • Quest for the simple SMTP Server
    Haraka Like: Simple to hook into the processing pipeline Dislike: Node.js and had some issues with stability when I last tried it. Source: over 1 year ago
  • Mailserver
    For the record, I'm using dovecot (https://www.dovecot.org/) for IMAP and Haraka (https://haraka.github.io/) for SMTP. Source: about 2 years ago
  • Is a 'dumb' self-hosted email server possible.
    Haraka (https://haraka.github.io/) is a plugin-based mailserver written in JavaScript. I've messed with postfix before but found Haraka easier because instead of arcane configuration files I can just read, copy, and tweak a plugin to suit my needs. Policies for receiving, storing, forwarding, and ignoring mail can be arbitrarily complex. Source: over 2 years ago
  • How to Monitor Exchange and Office 365 Mail Queues
    Exoprise leverages a node-based SMTP application, haraka, to process its messages as a well as series of custom plugins. You can read more about haraka here. Since its node-based its event driven, incredibly fast, and highly scable. Our auto-responders process 100’s of thousands of inbound and outbound messages each day, typically in < 10 milliseconds per each message. Source: over 2 years ago
