Is this for an Outlook/Hotmail type account? What do you have for the server settings under Tools/Account Settings/Outgoing Server (SMTP)? (For outlook/hotmail it should be STARTTLS security on port 587, normal password authentication, email address for the User name.)

If you have an anti-virus/security program scanning outgoing mail, disable that option and see if it helps.
