[Dovecot] Execute mailfilter after message move

Hi, came here to ask, if there are any ideas about a possible Dovecot feature, which would allow execution of a specific mailfilter or other program after new message is *moved* in specified mail location? The practical benefit on my side would be, that there wouldn't be any need to do getmail cronjobs, which unnecessarily fill up logfiles... (primarily for easy spam learning and reporting)
