The biggest problem with setting up new web services is getting to be able to successfully send email... (I've got a half-dozen solutions I use, but it's my main source of annoying sysadmin)
@lightweight tell this to the people who think emailing patches is still a good way to write software
@lightweight I've a lambda written that receives a POST request and just sends. Most likely not applicable to the situations you find yourself in, but it's removed nearly all that annoyance for me personally!
@lightweight is that because they don’t know how to talk SMTP to localhost where you have a Postfix null client?
@futuresprog I use a lot of Docker and in cases where the app uses localhost by default, I use MSMTP (a non-daemon Sendmail alternative) to talk to one of my Mailcow installations. Or I go directly to the Mailcow via auth SMTP if the app in question supports it. But currently wrestling with Piwigo refusing to send mail from my personal instance... :)
@MindOfJoe I also do that (I don't use a VPN, just SSH :) and HTTPS and SSL wherever possible). This is how I set it up: https://tech.oeru.org/configuring-linux-server-send-email-postfix-smtp-server-using-external-authenticating-smtp-host
