The only way I have found to delete blacklist entries is one at a time. Does anyone know how to delete multiple entries?

Look for a file called blacklist.txt, which should be (on an XP system anyway) in \Application Data\MailWasherPro\. This file contains both your whitelist (friends) and your blacklist.
Be sure that MailWasher is not open, then open this file using Notepad and delete any unwanted entries. The usual editing conventions apply, that is, highlight a block of entries via the Shift key, or highlight individual entries holding down the Ctrl key, then press Del to delete the highlighted entries. Be careful - you can't get them back. You could make a copy of blacklist.txt first, just in case.
