This may or may not apply to you, but if it does, there’s a quick way to filter out a bucketload of spam.

Spam can be sent to an address that looks like this:

dlsi.biz@proxy.dreamhost.com or valleau.gallery@proxy.dreamhost.com

instead of yourname@address.com (ie myname@dlsi.biz)

That is something in the form of  “address.com@proxy.yourISP.net”

What’s happened here is that the website has been placed in front of the proxy at my ISP.

Yours may look like amug.org@proxy.cox.net.

Well: no one I want contacting me uses that kind of address. Ipso – if the address contains “@proxy.myisp.net” I have set up a black list to just dump those emails. I never see them. If you can’t set up such a list via your webmail, then you can use it as a regular filter/rule in your email client.
