Why things happen is one of the great mysteries and joys of being a
sysadmin...
As for cleaning up SIS, I believe the "doveadm purge" command takes
care
of it. I have a daily cronjob which includes:
#!/bin/sh
# Permanently expunge old Trash
doveadm expunge -A mailbox Trash savedbefore 2w
# Optimize mdbox storage
doveadm purge -A
# Update fts indexes
doveadm fts rescan -A
