I would like to suggest expanding the MAIL FILTER option that is available to each mailbox inside ISPCONFIG's panel. Right now, you must select either a SUBJECT, FROM, or TO address for filtering. I find it useful to allow for something to filter out SUBJECT and FROM. Example: Everyone is annoyed when older, new email users forward crap all the time. It would be great to be able to add a filter so that any email from GRANDMA with the subject containing "FW:" could be MOVED to a specific folder like JUNK, TRASH, FW EMAIL, or GRANDMA.
