Email
All my servers use an SMTP relay to communicate via email. I have setup “service” accounts that they use to authenticate themselves on a smarthost. My OmniOS server is no exception.Continue reading...
Looking at my notes , it seems I haven’t setup an email services server from scratch since 2015. Of course, mine have evolved following OpenBSD updates and upgrades.
Let’s benefits from the fact that I’m migrating from Vultr to OpenBSD Amsterdam to write a few notes about the mail server (re)creation. At the time of writing, OpenBSD is available in version 7.2.Continue reading...
