> But how much time do you spend dealing with that? Is it worth it?
Not much, maybe on hour per month at most. I've been running Postfix on a dedicated server for 20+ years and don't need much time dealing with it.
But I've made sure to keep the same ip address when upgrading servers (possible with Hetzner) and besides configuring postfix to reject various connection attempts I do run spamassassin. Resulting in about one or two spam mails per week (moved into their own box by procmail in the filter chain) which I handle once a week by training spamassassin (takes just a minute).
