Thanks for replies. silverous - Outlook has a blocked sender list which at least stops repeats. Bullguard is similar to other anti spam programmes and includes the things you mention , but I thought I had read somewhere of a programme which only "allowed" e mails from people in one's address book. DieSse, p;3 -I will look at the other programmes but word filters are by - passed by spammers sending photos of words rather than text. Ideally I don't want to have to sort mail from "strangers". I'll probaly resort to changing my e mail address.
