My goal is to have separate wireless networks for guest and IOT devices, each on there own VLAN. Setting up VLAN with an EdgeRouter, UniFi switch and UniFI access points takes a few extra steps. In this post I describe how I got it working.
With Debian 10 (buster) the default firewall is nftables so it’s time to convert my iptables rules. Since Debian stable is never first with anything I was surprised to see how relative few articles and blogs there are about nftables compered to iptables.
Ansible role with commentary for setting up your own mail server with Postfix and Dovecot. This could be considered a part two of Mail relay, MX backup and spam filtering with Postfix. Many postfix configurations are identical between these setups.
If you run your own mail server it is a good idea to have a MX backup in place. When your mail server goes down or you need to upgrade it, the MX backup will step in and store all mail until the mail server is back up.
Setting out to create a simple contact form turned out to involve more work than I anticipated. I need it for one of my new static sites. The examples I found was to old, lacking spam protection and/or relied on multiple/large libraries.
I prefer to store (archive) my mail locally. After moving my mail between mail clients a couple of time to many I decided to set up a local IMAP server. This will give me a mail client independent local storage that is in a standard format and future proof.
