If you have an IMAP based email account with hundreds of megabytes storage space (like the one I have at Fusemail), it may seem like an infinite space at first. But after using that for sometime you will find it filled up with a lot of small emails 1~2megabyte emails. That's what happened to me until I used IMAPSize. With IMAPSize you can easily see how much space each folder is using, sort the message based on their size, and delete messages or only remove the message attachments. It can also be used to get backups and some other tasks.
Btw, why don't GMail sort messages? Or at least I don't see any option for it.
