Apparently, the admin of that mail server is only accepting mail from domains that are on a List of Approved RCPThosts. It seems as if your domain name is not on that list.
Do a whois on their domain name & speak to the admin. -Michèle Immigration site: <http://LadySun1969.tripod.com> Our new 2001 Miata: <http://members.cardomain.com/bpituley> Tiggercam: <http://www.tiggercam.co.uk> --------------------------------------------------------- Sports Commentary Gem: "This is Gregoriava from Bulgaria....I saw her snatch this morning and it was amazing."
