Ok, I suppose I could have figured that out from the headers. I am just asking because I know AOL, and some other ISP's were "blacklisting" certain domains. It is very easy for a domain to end up on the "blacklist" simply by passing a virus or two inadvertantly. Once they are on the blacklist it takes months to get off of it. Ask hometel if they blacklist addresses at all and if the addy you were trying to send to was on the list. Just a thought. That is definitely an issue with the ISP though. Their server is blocking you from sending to that address for some reason.
