I am a complete noob to the stuff a lot of you guys are talking about here and would like some help on understanding the purpose of the courierimapkeywords folder in my mail directories. I am finding a directory in my /mail folder as well as in may /mail/Trash folder, both of which are at least 45MB in size on one of my users domains. I do have Box Trapper enabled, as well as Spam Assassin, and I am sure that the courierimapkeywords folder has something to do with one of those programs (based on some of the threads I have read here). If someone could provide me with basic information, specifically on how I can reduce the size of these folders (I tried deleting via FTP and the folders recreate themselves), I would be grateful. Some of the resold domain accounts I have set up have only a 250 MB limit, and with two courierimapkeywords folders containing 45MB of files each, you can see where their limit will start getting eaten up pretty fast. I appreciate anybody's feedback or assistance.
