Thank you for your reply. I'll try to reset the port and smtp server. I recently got this working (although only temporarily) by installing a free smtp server, and configuring the settings in IIS to run from localhost, but the particular server I'm using limits me to 10 emails a day without buying their full version. Does anyone know of a reliable (preferably free) smtp server that allows fair traffic? We're not sending spam, but we'll certainly need to send more than 10 emails per day, so an unlimited allocation is best. Thanks.
