It looks as if mail for bellhouse.org.uk and smofs.org is arriving OK but is not being delivered to my mailboxes. I have raised a fault with soho-uk.com, who host these domains for me, but responses will be delayed until I actually see the mail.
In the meantime, I've set up a yahoo account: tim_illingworth at yahoo.co.uk
