Here's how mail delivery normally works:
1. Message is composed, and sending is initiatied.
2. (Optional) message is handed off to a MTA, this might be local, remote
via SMTP, or a separate part of the same application.
3. The domain part of each of the destination addresses is queried for an
MX record from DNS; if no MX record exists the A record is used instead.
4. An SMTP connection is made to the host (MX) or address (A) and the
message is delivered there.
5. The MDA on that server decides what to do with the message. The may
involve forwarding (going back to step 2), local delivery (THIS IS WHERE
THE VIRTUAL USER TABLE [or equivalent] IS QUERIED), or other actions.
6. Once final delivery is made to a mailbox (or the mailboxes), the
recipients use POP, IMAP, Web, mbox, maildir, and/or other methods to read
the mail.
Does that help?
If you are truly isolated from the internet, you can indeed make sure that
the DNS MX record for yahoo.com points to your MDA and deliver
[EMAIL PROTECTED] to a local mailbox, but it involves more than just your
virtual user table.
