This looks like the direction you need to go, that message is usually caused by a overactive spam filter.

• Pop before SMTP -- Run a check for new messages (F9 key in Outlook) before sending your message and restart and rerun your spam filter application. Your IP address is entered in a relayhosts file, allowing email to be sent from your address for up to half an hour.
• If the problem still persists check "my server requires authentication" to authenticate automatically. With this setting you can bypass the check above and send mail without having to "pop" your mail box first. You can also try changing the outgoing port from 25 to 26, since some ISP's block this port.
• Several of our readers have pointed out that it may help to remove apostrophes from your email account names (and ask senders to remove them if you're having trouble receiving emails from them).
• If you're on a VPN, try disconnecting from the VPN prior to using your mail program.
• Your mailbox may be full - try clearing out messages or asking your mail service provider to increase your mailbox limits.
• If you are using multiple mailboxes, make sure these fixes/ settings are applied to each one of them, especially the "default" one.
• Finally, if using a mail screening utility such as Mail Washer, you may want to disable the "automatically check at intervals" setting and check mail manually. If the system checks mail while you are sending you may get this error
