Email for self hosted services? (Not personal email) (lemmy.today)

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

If its internal network traffic only, you can just use stalwart and add the DNS records to your network so that stuff can use SMTP.

Otherwise, (also with stalwart or your preferred software), you will want to use an SMTP relay so that outgoing messages will be delivered without the hassle of getting your domain reputational enough for sent messages not getting junked by the big email providers.

I'm extra lazy and haven't set this up, so I just have a public mail server that only receives messages because my outgoing SMTP port is blocked by my ISP.
