Not getting some e-mails

I use Microsoft Outlook as my vehicle for getting e-mails. I am not getting some e-mails from the Pittsburgh Steelers--they are mass mailings without a inbox, so I can not send an e-mail to the address that is sending out the messages.  I've talked to Comcast and to the Steelers--no help to resolve this issue from either of them.  Anyone else have this problems? Any suggestions?
