OK, just to clarify. I have a business website which is hosted by another ISP - not BT. With this host I have an email address to which mail is sent.
I also have the BT Broadband service which I use for the ourpose of using the internet. I have an email address - my primary email address as BT calls it where other personal mail is sent.
For convenience, I have set up a BT email account to pick up mail sent to the business host, which is what I have rightly or wrongly called mail relay. this works just fine using Outlook as the mail client.
My question therefore was, if I am not in my office, connected to BT via the ADSL line, could I have the same set-up, i.e. by using BT web mail to collect mail sent to both my primary email address (this woks ok) as well as the other mail address.
Thanks for replying
