We found that there are historically corrupted mails in the tmp/ directory, For example, Maildir/tmp/ or Maildir/.Drafts/tmp/ exists.

Not sure what the problem to fix would be though. It should be safe to just rm those files. When dovecot is moving/storing mails with maildir, it will first write them under tmp/ *and* if the operation is succesful, then they are linked to destination and unlinked from tmp/.
Can tmp/ directory mail be stored for a long time? Can dovecot handle tmp/ historical mail by itself?
The tmp/ directory in Maildir should never contain anything for longer than a few milliseconds.
If anything is in there, there was some kind of error or interruption in the past (the ctime of the file should tell you, when it happened).
As Aki said, the files can be deleted safely. You may want to check if the contents of the file are equivalent to any other mail in the Maildir in question or manually move the file to cur/ on your own, to make the mail visible to the user.
If you have many files in tmp/ then something is wrong with you system or storage and you need to investigate this, since this is absolutely not normal.
