Phil,
What is the SMTP server name your friend is using for their
smart relay?
Are they on a Freeserve/Wanadoo Broadband package?
Wanadoo use tranparent proxying on port 25, if the server is
not the one they want you use. However the transparent proxy
mail servers are listed (at Wanadoos request) as being a bit
dodgy, likely to be a zombie sort of thing.
Probably nothing to do with SPF, after all BT can hardly manage
to do anything with email, even delivering it, and do not deal
with abuse. The recent joint announcemnent about dealing with
spam by sorting out local issues, did not include BT, despite
press (mis)reportings, complete wasters.

A few weeks ago, a friend (here in the UK) had a problem
sending email. They
used to dial up through Freeserve, but then they got broadband. I set up
their network so that the broadband was shared, and they could use the
office ocmputer to browse the internet and send email without
dialing up.
Everything was fine until they got a bounce message with an
3-digit error
code that I can't remember, but the text description was "Administrative
Denial". I think the recipient email address was @btinternet.com.
I scratched my head, searched the internet, and eventually resolved the
problem by setting up their mail client to dial Freeserve when sending
email, and then everything was fine.
I suspect that BT Internet were rejecting the email because the
'from' IP
address didn't check out. Could this be SPF-related, and if so,
can they set
up an SPF record to get around it?
