@necrevistonnezr True, but imapfilter ( or another workaround ) is here today for you to achieve what you want. Beats waiting for the feature you're asking for which might be available sometime soon, later .... or never.

@necrevistonnezr I actually wrote a post about migrating email hosts using the imapsync tool that girish recommended, you can check it out here. Note that my post is a bit more extensive as I also migrated registrars and had other active emails there that weren't mine, so yours should hopefully be a bit easier than the whole tutorial!
