  • 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
