In part 1, we talked about your POP server settings. Now, it’s onto SMTP which is another setting you’ll have to add when configuring your email software. SMTP is another protocol or set of rules and this one is for sending your email. SMTP, or Simple Mail Transfer Protocol, is the set of rules your mail software (like Outlook Express or Windows Live, for instance) uses to send your mail from your computer to the mail server where POP will take over and get it to the correct recipient(s). Very simply, your email software uses SMTP to first connect to the SMTP server you’ve set up the email software to contact (most likely, the one that your Internet Service Provider has given you), then to tell the server “hey, I’ve got some mail here for someone”. It then sends the mail to the server and finishes its job with the Quit command. Your email has now left your computer and gone out in the world. Hope you didn’t just send it to the wrong person by mistake. Send carefully!
