Can I send to a fax number using SPUtility.SendEmail?

We are using SPUtility.SendEmail to send notification emails from our SharePoint 2010 application. We were hoping to be able to use this with our fax server and just send [Fax:0121XXXXXX] to SendEmail as the address.

Now I can see that this does not work as it gets treated as SMTP and not FAX type.

Is it possible to use SendEmail or another SharePoint method to create emails which are actually FAX type?
