How do I know this? I grouped all of my mail archives into one Maildir last night [1]. Before I did that, I moved /home to a new 100 GB partition [2]. And that's where learned that trick. Google "ubuntu home new partition"; the first result is what I used.
[1] Swarpa folks, I'll clean out my Maildir shortly and give you some MBs back - I'm just going to double check a few things first.
[2] No, I don't have that much mail. But I have a 500 GB hard drive, and it's still not all partitioned, so why not [3]?
[3] The best thing about a 500 GB hard drive? Unless you start messing around with uncompressed audio, lots of video, or serious photography, you don't have to delete anything. Ever. I have a partition that, among other things, has the entire contents of the hard drives that used to be in my two ancient servers. I could go through and delete the old OS installs, but why bother?
