Free SMTP server for use with Dell IT Assistant

I have legit reason for looking for a free SMTP server that does NOT requiire authentication.  We are trying to get Dell's IT Assistant to send an email but our remote site uses POP and their SMTP server requires authentication which the ITA app does not allow you to provide (or I have not found a work around).  

Thank you!

If you have a Windows network with any version of client Pro/Business (XP Pro, 7 Pro, Vista Business) or you have a Windows Server, why not use the built-in SMTP server of IIS?

If I configure the IIS SMTP server to point to an external STMP server, will this affect mail flow destined for their existing mail server?

To clarify, IT Assistant can send email alerts but does not allow me to provide l/p information for any smtp server that requires it.  We will be sending the mail alerts to  I do not want other emails to the same domain to go through the same SMTP server - rather their existing mail server.  So mails sent to should not be used by the IIS SMTP server.  

Would this work and is this difficult to configure?

SMTP on IIS is not my best subject.  In general, it's easy to configure (I'm always paranoid about open relays, but it is securable by IP address).  I definitely have configured it on numerous occasions, though almost always for INTERNAL use only (don't know if you expect to expose it to the internet.  If it's just for SENDING e-mail, you can keep it behind a firewall and not permit outside connections and you should be fine).  

Unless you change your MX records, there should be no impact on any other mail functionality.
