Wilko, Error message “Relay access denied” usually means you are trying to send email via  an ISP which is not the one you are connected to at that moment. Check the reply address you have set for your emails. As has been suggested it’s best to set up your own domain with a host that includes email facilities, I use 1&1, it’s not expensive at £0.69/month. For this you get 5 Pop3 mailboxes which allow you to send and receive fom any ISP anywhere.+ 100 forwarding addresses. You would need to set up your own domain which costs £2.24/ year for co.uk, other domains such as .com eu etc. cost more. All prices +VAT. You might find that your first choice is already taken in which case compromise is necessary. Another advantage is that spam is far less likely – it is targeted at the big boys such as AOL etc. www.geo-web.org.uk
