Migrate iRedMail to Mailcow

I've been eyeing Mailcow for a while since it's use of Docker should ease the maintenance and update burden (you iRedMail users know what I'm talking about lol) and bring a better UI and user experience with it's admin panel. Here are some notes that I took from my migration in case it helps anyone else out.

I setup a Mailcow instance on another server so I could keep iRedMail operating during the migration. After it was completed, I used Mailcow's backup and restore feature to move it to my original server.

Migrating has three main parts, mail, contacts and calendars, and DKIM. There's also some configuration which I'll touch on too.

BCM4350/DW1820A/XPS 9350 Wi-Fi Fix

If you are using a BCM4350/DW1820A Wi-Fi card or an XPS 13 9350 on Linux, you may have run into an issue where your Wi-Fi stops working after suspension/sleep. Hopefully my hours of research can help you.

The Problem

It appears there is some kind of power management problem with this card. There are several different threads documenting these issues (I'll link them below). These issues were officially resolved sometime around kernel 4.19 but I'm still experiencing them and I imagine some other people might be too.
