Which mail service are you using ?
Why don't you log into your mail using any browser and add filter or block the mail sender ?
I'm using "Mail" on my iMac computer. In terms of your suggestion to log into my mail using nay browser and adding a filter, I don't know how to do that on a Mac.
Ok I will help you in that
Please let me know which mail service are you using ?
Like Hotmail, gmail, Yahoo mail etc ?
Well, my primary address goes through earthlink but I also have addresses that go through me.com and mac.com.
If you can get into earthlink mail using a browser
you can filter out those mails or even block the mail address from which you are receiving junk mail.
Refer these two links to do that.
Let me know how it goes.
