I just recently got a virtual server with plesk. I need to figure out what I need to tell my customers to enter for their outgoing server. I have my server with godaddy. They told me to use k2smtpout.secureserver.net but this creates an error. Godaddy said that this is the outgoing server to use in Plesk but that doesn't help me figure out what to tell my customers to enter in the Outlook Express program. Please help. I am very new to this. Do I have to set up an outgoing server? If so, how in the world do I do this? I'm using sdwebserver.com as the nameservers for hosting.
