Problems fixed in this Hotfix

This MIMEsweeper for SMTP 5.2 Hotfix provides solutions to the following problems:

When SpamLogic auto-training was enabled, it could in some circumstances increase the number of false positives; that is, the number of emails incorrectly classified as spam.
When you create or edit a PCS LDAP address list, you can test the results of the query by entering an email address and clicking Search for User. This test sometimes incorrectly returned a message saying that the current configuration does not include the specified email address, when in fact the address you entered was included in the query. (This problem only affected the Search for User test result. A valid address was included correctly in message processing.)
The Identify Policy dialog (displayed when you right-click Policies in the Policy Editor and select Identify Policy) matches a route, consisting of sender and recipient addresses, with one or more scenario folders. If an address that you specified was in a PCS LDAP address list, Identify Policy sometimes failed to find the address and could therefore return an incorrect result.

This Hotfix also includes the following enhancement:

SpamLogic now provides improved detection of URLs that may identify an email as spam.
