Question : 553 sorry, that domain isn't in my list of allowed rcpthosts; no valid cert for gatewaying (#5.7.1)

I am staying is a hotel and they offer internet service for the room.  I use MS Outlook and the out going server is "smtp.theparkwayhotel.com".  I have checked with the IT people here and they said I do not need authentication checked.

I get the following message on an imdediate send back message: 553 sorry, that domain isn't in my list of allowed rcpthosts; no valid cert for gatewaying (#5.7.1)

Please help ASAP!
