No, that's not the issue at all.  The issue is that there is typically nothing the local network can tell you about, e.g., which SMTP server will work with your email address, or which POP or IMAP server might store your email.   In the general case, those services are not even present on the local network, so the local network has no way to tell you about them, and even if it did, why would you trust it to do so?
