[Help] Setting up your own e-mail/smtp for alerts? (lemmy.world)

submitted 1 year ago by mumblerfish@lemmy.world to c/selfhost@lemmy.ml

Hi,

I'm looking for some way to send my own alerts via e-mail in some way. Whenever I try to search for this, most docker images have a much grander goal, and I have a hard time understanding how to use them for my purpose.

What would I want? It'd be nice to have a docker running some smpt-server (I suppose), so that I can make my own python script that scrapes a website, looks at some metric, and e-mails me whenever whatever I'm looking for is found. I only want it to be available on and to receive mails from localhost, no dns, just forward e-mails to my personal one, no web-interface, etc.

I'm quite new to self-hosting, but I hope you still understand what I'm looking for. Is it possible? Should I look for another solution? Will this not work? Any help/input very much welcome.

Postfix can be configured to only listen on localhost. Most things can be, actually.

Ah, postfix looks like what I'm looking for, thanks. Have to see if I can figure out how to configure it.
