Well, no. The MUA has usually already sent the mail to the Drafts folder before the user hits “Send”. When the user hits send, that same file is moved to the Outbox folder; When the MTA indicates success, it’s moved to the Sent folder.

Unless you’re using mailbox quotas, there’s no effective size limit on the size of a file in the Drafts folder. Unsent email is a nice handy-dandy free file storage mechanism.
