I use Non Spam Collection Frequency
Store every n'th non spam message. If you set the value to 10 then every 10th message is logged. These frequency settings are for ASSP users with a mature installation who experience heavy mail or spam volumes. Enter a larger value if the non spam corpus is being refreshed too quickly. Default Value = 1, log every message. Spam Collection Frequency Store every n'th spam message. The same as for non spam but helps prevent spam corpuses being skewed by flooding. It is recommended that this be set depending on spam volume. Default value = 1, log every message I have the reverse of your problem. Lots of spam, little ham. You can always do a 3 non spam 1 spam to bring up your weight. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
