The British Caving Association

Yahoo which includes BT & PlusNet are bouncing email sent from the BCA Server with

554 Message not allowed - [PH01] Email not acceptable for policy reasons.

I'm working on this but no resolution yet.

I've checked we are not blacklisted on any of the spam servers - we are not.

So this is a Yahoo thing.

OK I think it is solved.

The solution involved renaming the server from britiac2.miniserver.com to server.british-caving.org.uk

The miniserver.com domain hosts many other domains. One or more of those domains had upset Yahoo. By changing the host name we are now seperated from that.
