#7 Really useful thank you Paul, my main email address is on my own server so not a problem but certainly worth considering my choice of name for others.
Another thing that I found works well is if you get lots of spam for certain things - such as pharmacutical companies offering cheap viagra (common spam so I have heard but have ABSOLUTELY no experience of!
) then create a 'rule' in your mail client that sends any mail containing that word to your spam folder - just be careful which words you chose or you could end up sending genuine mail there!
