managing email server with filter to folders

I'm looking for a solution for managing emails from my domain shared with other colleagues on the team.

I would like to manage incoming emails by dividing them into folders in IMAP based on filters, example: if it contains "orange, apple, pineapple" move it to the "fruit" folder ...

this mail server or similar solution will have to download all mail from the remote server and sort it, sending only by external SMTP. The mail server or the one that best suits the case will not be configured as an MX server and with all that comes with it, it will only be a means of managing emails.

Are there any solutions that can be adapted to my case?
