1. Pop before smtp - check your email account for new mail before trying to send email. This adds your IP address to a relayhosts file and allows any email to be sent from your IP address for up to 30 minutes. After 30 minutes you have to authenticate again. You may also have to authenticate again if you are disconnected from your dial-up connection. If you are using Outlook then under Email Accounts within the more settings for SMTP you can select always check email first.

2.
Configure your email client to authenticate automatically by checking the "my server requires authentication" box in your email configuration, then check the box that requests that you check your incoming mail before sending outgoing mail. You will be able to send mail without having to manually check your mail box for incoming mail first.
