Sending to this 1 e-mail, get error saying my IP address blocked?

[Mary Mak]

I am sending and e-mail to one particular address and I keep getting an error:
A message (from <[email protected]>) was received at 7 Oct 2009 4:51:07
+0000.

The following addresses had delivery problems:

<[email protected]>
Permanent Failure: MAIL FROM: <[email protected]> 550 REPLY:
550_SC-004_Mail_rejected_by_Windows_Live_Hotmail_for_policy_reasons._A_block_has_been_placed_against_your_IP_address_because_we_have_received_complaints_concerning_mail_coming_from_that_IP_address._If_you_are_not_an_email/network_admin_please_contact_your_Delivery
last attempted at Wed, 7 Oct 2009 04:51:07 -0000 - I have never sent any bad
e-mails and I'm the only one who uses this account. It's just this one user
I have problems with and it just started - any advice?

Hotmail has been having some problems with blocking RoadRunner/TimeWarner
e-mail accounts lately. Supposedly this was fixed on the morning of the
5th. http://security.rr.com/help.htm

This is not an issue you can fix. The mail server used by your receipient is
rejecting bellsouth (AT&T/Yahoo) server IP addresses. You should contact your
AT&T support people and tell them or contact your recipient and have him or
her tell the people administering that mail server to unblock your server's IP
address.
