I was doing this. But then I started noticing that some emails I had read were not being stored locally in the Thunderbird IMAP folder structure on my computer, even though Thunderbird had fetched them and shown them to me. I couldn't figure out any rhyme or reason to this, so I started using mbsync on the commandline to properly mirror my IMAP account to a local store that then gets backed up with my home directory.

I use Thunderbird and just back up my home directory.
