It would be great if the ISPConfig3_Filters addon could have filter rules created and then be able to have it run and filter out already existing messages rather than only filtering new incoming messages....kind of like having the filter rule catchup with what's already in the mailbox. This would help clean up mailboxes that are quite large.
These functions exist in the email clients, I don't see why one should implement that in ISPConfig, especially as one would have to write a whole email parsing engine etc. for that.
Ok. Just if users are only using the web to connect to their email or even using an imap client on their phones, this functionality is not there. Never hurts to ask.
