I've just installed Exchange 2003 Server (SP1) on Windows 2003 Server. I'm
having a problem sending email to Hotmail.com & other domains. The error is
'The connection was dropped by the remote host'. What's strange is that
sometimes it works using Outlook 2003 client. It always fails using OWA. I'm
using a SonicWall TZ 170 Firewall Router.
Any ideas anyone?
