We provide an example of configuration in some e-mail software as follows.

In the above example, we explain the use of KUMOI by IMAP. In general, e-mail software does not store your e-mails in your PC when using IMAP. If you want to store them, you need another configuration in your e-mail software. The configuration may be found by searching webpages with keywords of "[your e-mail software] imap backup" or others.
