When you have that much spam coming in the transition between
cleaning up with MailWasher and then pulling in your email with Outlook
Express is still going to result in pulling in several SPAM messages
that MailWasher would have caught.
It would be best to have them removed by the ISP provider, if possible.
Root around your ISP for junk filter, then even MailWasher
won't have to deal with most of them.
MailWasher won't deal with hotmail unless you pay extra so the following
will directly ihelp those that have a hotmail email account, and those that
have an MSN account. But it might help you to locate what is available
on your own ISP.
