so just post your mail addy on a public site and open up your outlook (express)..
be sure to enable the preview function.. and you'll be sure to get infected..
Sobig.F doesn't exploit any flaw in Outlook. So enabling the preview will not get you infected. For Sobig.F to infect your machine the user must run it. But you don't have to infect your machine to analyse it. Just be on the lookout for emails with an attachment that ends in .pif or .scr. Save this attachment and start analyzing.

See the Virus Information Library for more details on how to recognise Sobig.F.
