Somehow e-mail from a hotmail account is being resent to my comcast account and it’s not my hotmail account. How can I get this changed?

I started to receive a ton of e-mail this morning to my Comcast e-mail account. It appears it was being sent to various people, none of them me. I contacted Comcast customer support and they said that all e-mails from this hotmail e-mail address (*** Email address is removed for privacy ***) are being resent to my comcast account. I've setup a rule to move it to my spam folder but I'm wondering if there is anyway to permanently stop it from coming it at all and removing my e-mail address that is being used to resend all of these e-mails to.
