[Exim] Contact Details- BTinternet

Hi All,

Does anyone have any kind of contact details for the guys at BT that
maintain their mail servers?

Specifically:

stargate.btinternet.com

I have called loads of different numbers and been given email addresses that
bounce and still no response from
the email I sent to postmaster@???.

Only relevance to exim mailing list is that I believe they use exim.

Cheers

Ed St Pierre
