Manually patched my mail server because I just realized it had a 2020 bug. All emails with date in 2020 were being given points for "date grossly in the future". I kinda noticed an influx in false positives and decided to investigate more and realized that.
I really should update that server. OS install date is 2008 and I've just been lazy. It's the mail server and mail is a pita to setup. I have a couple custom things setup so it's not exactly a standard setup, and right now it uses Unix accounts per mailbox which is really dirty but my custom code does not work if I go with virtual mailboxes, so I have to code my own mail transport program and then the project kinda stalled lol. But yeah I need to get on that.
I eventually want to write a program that presents a front end for configuring all the standard Linux server stuff like mail, users, virtual hosts, etc... so I keep telling myself I'll just wait till I code that, and yeah that's been on the backburner for a bit. I started to play around with how to create my own custom Debian install disc though, as once I have that basic process down path, it's just the thing of adding my custom software and I have a really quick installer for bringing up a new server. Then upgrades would just involve remastering it with a newer version of the OS and my software would just pickup the old config files and regen the Linux config for the new distro.
