  • How to map Traefik2 generated LE certificates to Poste.io mail server?
    I've done the same on my VPS. The only difference is that I used docker-mailserver not poste.io. Source: 7 months ago
  • How to map Traefik2 generated LE certificates to Poste.io mail server?
    To my specific issue. I've had a small VPS hosting only the mailserver poste.io via docker-compose, that worked well and certificates for multiple domains were taken care of via poste's internal let'sencrypt support. Source: 7 months ago
  • Poste.io problems, cant send emails
    I am using poste.io on two other servers and they work just fine. I thought maybe its because of newer version, but downloading older versions doesnt seem to help. I can receive emails but I cant send them. They get stuck in the delivery queue. Source: 11 months ago
  • Need advice fixing my embarrassing email configuration.
    I've self-hosted my email for the last ~6 years, at first using mail-in-a-box; but more recently moving to a containerized poste.io instance. I don't have any issues with delivery; but it's likely due to how long I've been in existence. Source: about 1 year ago

  • 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
