Relaying Problems

[TalentedFool]

Hi Guys, I've cross posted this under the Exchange group as well, but hopefully one of you guys will also have an idea... does anybody know what the following means ?

We're running NT4Sp6 with Exchange 5.5sp4 - I've dealt with the open relay problem so thats out the window.

One point . - the address focusint.demon.co.uk - out mail server knows nothing about! is this an ISP problem and if you think it is - why is it so I can shout at them!

Cheers
