spamcop refuses mail from where I work

[phoff2824@spamcop.net]

If I send email from my work exchange 2000 server to my spamcop address , I get this error message.

"The following message to <xxxxx> was undeliverable. The reason for the problem: 5.1.0 - Unknown address error 551-'This is not a relay host - mail must be to or from host domain.'"

However, if I send email from my hotmail account to my spamcop address it goes OK. I can also send email from my work exchange 2000 server to my hotmail account OK. What is it about spamcop that rejects my work exchange 2000 server email?

Thanks,

Phil
