One of them is Yahoo. Not too worried about that one. The other is "Outlook Express 6" on "Windows XP" The outlook has a block feature but there are so many on there already it takes a while for the thing to pop up when you click on it. And these spammers just keep changing there names.
Sometimes I wonder if it is possible to send them all this stuff. Just combine all the junk mail and send all of it back to all of the spammers.
Google is the best. And it's free. Most spammers are very clever and use phony addresses that prevent you from mailing back to them. You have to be a sleuth to track down where the spam actually comes from. Most of it comes from Asia. Outlook's block feature doesn't work very well because it doesn't analyze the content of the message.
I have Verizon for one of my e-mail accounts and they have their anti-spam software turned up so high that it often deletes messages I want. Most ISPs offer spam blocking. Some are better than others.
If you're using yahoo, I recommend switching to google.
