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.
Sorry, I must not have explained myself very well. I guess it is the part on receiving on localhost. What I meant to say was that I would like the smtp, or whatever, to only be available on localhost, so that no one else on the network can use the service to send e-mails.
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.
ArchWiki, as always, is amazing.
