Don't tend to get much spam. I use the unlimited e-mail address function anything@... with my domain name to 'personlise' accounts.
So the company name will be the first part of the e-mail address alwil@....
Anyone that sends me spam, when I have SPECIFICALLY ticked (or unticked - watch for the catch) the box gets blocked.
INCIDENTALLY this is how I came across AVAST as I had signed up for 12 months with Norton - Sygate or whatever the idiots call themselves norton@...... the amount of spam sent to that address .... (from Norton) was stunning. When I complained, and I said I knew it was from them (after about a month and £65 or whatever it was then) they said tough ......... they had my money.
Erased Norton that day, then installed Avast, that was 2 years ago.
NORTON - GET STUFFED!!
I Feel better now
