Several of my self hosted services need to be able to send minor occasional emails for things like changing passwords or other notifications.
I’ve never been interested in the hassle of self-hosting my personal email, since I’ve heard about it being difficult. But for my little local services to have one admin@ or noreply@ to send from, with just a small handful of friends and family as users, maybe it’s simpler than a full personal email replacement would be? I’m not too concerned, for example, if they have to check their spam folders. As long as the email still lands. And probably wouldn’t need to worry about incoming emails.
What are you using for this type of thing? Hoping to have something not too complicated, and FOSS.
Edit: I also would like it to come from ____@mydomain.com
My ISP offers unauthenticated SMTP for their customer addresses. It’s pretty heavily rate limited, but well enough for the occasional status email my system throws out. At least around here they are pretty common for residential customers, so that might be an option.
Other possibility is to set up SMTP relay to your network and give it credentials to an actual email account (with SMTP support, which isn’t granted these days). It can take in emails from your network without credentials and throw them to the internet with your account. It’s pretty simple to set up, search for postfix + smarthost. Added bonus is that you can read the replies to that address too via your email provider services.
