How to Have Windows Mail or Outlook Express Send Mail Immediately

If you send a million emails in an hour, that should get noticed. How, then, do spammers go undetected?
Spammers send the million messages from just about as many different — hijacked — computers. It's almost impossible to spot these machines, all of which deliver maybe 2 or 3 junk emails per day.
One way to deal with these spam-spouting botnets is to slow down email for everybody. While your typical email program will readily wait a minute or two to deliver a message, spamming tools quickly give up and go elsewhere — at least as long as they can find places that accept mail instantaneously.
Speaking of email delays: what if your Windows Mail does not wait a minute or two to deliver messages but until the next time you check for new mail?
›› Make the emails you send go right to their recipients instead of just to Windows Mail's or Outlook Express's "Outbox" folder.
