If you're using Mozilla Thunderbird to manage your email, this is important. Right-click on your folders, one at a time, and select "Compact This Folder." Don't worry, it's safe. It seems to flush out messages that were deleted, but still take up space in the mailbox
My mail folder was over 100MB for one account, and after compacting my mail folders, it ended up just over 40MB. Certainly worthwhile to remember to do every once in a while.
