James,

They stop you sending email though their SMTP servers to prevent
spammers relaying through their servers, I think this is probably based
on IP address. Most ISPs SMTP servers will not check the reply address
if your IP address is from their dial-up range of addresses, outside of
that most will probably block unless you email address matches their
domain.

Some ISPs like FreenetName for example stop you from doing anything
unless you have dialled up with them i.e. POP3 and FTP access to your
webspace. I had a domain registered with them which was ok while I was
on dial-up as I used them as my ISP, when I got broadband 3 years ago I
found I couln't get to their POP3 of FTP servers from NTL so I gave up
on them. They have deleted my website and now want =A394 to sell the
domain to me. I had bottrill.co.uk, I recently bought bottrill.org for
$32 per year with dynamic DNS service. For a further $20 I have a backup
SMTP mail service for me for when my server is offline. I'm well chuffed
with the service.

If anyone is interrested I use www.no-ip.com their basic service is free
but all you get is a subdomain from one of their registered domains I
used to have bottrill.no-ip.org. You then download a small program that
logs onto their servers every 10 mins or so (configurable) so they can
capture your IP address.
