Cannot remotely send mail.

[Eric LaLonde]

since my last post, I've now set up qmail on a different box that doesn't have port 25 blocked. i've set up a pop server to receive email from a remote location (vie outlook or whatever other client the user has), but I am unsure of how to send mail from a remote client. It simply fails when i try to use the server to send mail, from a remote client. what do i need to add to qmail to enable this?   - Eric
