Many users wish to send email through the department server when they are using computers outside the CS network. Typically this will result in a relaying denied message; relaying email in this way is a common technique used to send SPAM. User's wishing to relay their email will need to use SMTP AUTH/STARTTLS, which allows only users with valid CS accounts to relay email through the department server from outside the CS network.
