Mailwasher is certainly a first class product, it allows a sneak preview of suspect e-mails whilst they are still sitting in the server to check if they may be viruses and makes it a simple task to delete them since most of the spam is marked for bounce and deletion automatically. I have also found that the junk seems to be on the decrease all except the porn, especially "farmyard sex" and since I have never opened any of these mails or visited porn sites, I am not sure why I should be receiving unsolicited and unwanted mailings at the rate of two or three a day!
I sent my $25 to the author of mailwasher in the hope that he may be encouraged to develop mailwasher and others to end the curse of spam and pop-ups!
