The code I\'m using:

Your client code looks fine, the problem may be in web.config:

host="mail.OurOrganisationEmail@ourdomain.com"

it's an email address, not a valid hostname it should look like this:

host="mail.ourdomain.com"

Have you tested if the smtp server works ? just make some basic tests using telnet. http://technet.microsoft.com/en-us/library/aa995718(v=exchg.65).aspx
