I can't say thank you enough for MailWasher pro. It has help eliminate spam in my emails to almost nil. And I was getting alot of spam. To the point that it was making me sick to open my emails. MailWaher changed all that along with 2 free programs I use. IPNetInfo and Abuse. This 1-2-3 punch works great. Abuse is a program that scans the headers of the spam and then gives you the ISP the email originated from. It then let's you select a preconfigured complaint letter to send into the ISP Abuse Dept. IPNetInfo allows me to trace the other IP's in the header so I can report to the ISP's that are being used along the way as well as websites that are being used by these scumbags. Google, Yahoo, and MSN get used alot by the spammers for forging addresses. I actually look forward now to getting spam so I can report the idiots to their ISP's and have them disconnected even if it is only for a short time. But, these 2 free programs are useless without MailWasher in my opinion. All 3 together work seemlessly. here's the link for Abuse if you want to check it out. I am in no way associated with the program. I just believe in it. It has worked wonders for me.
