Clicked Email SPOOF now I cant send or receive email

I just clicked on an email from ebay, and since then my outlook express email account will not send or receive. Somehow it affects a different computer too, so it seems it somehow affected my website's server. Also, when I went to my website's control panel and tried to send with their web based email program, it didnt work either. My other email accounts work ok. Is this possible? HijackThis, CCleaner, SPYBOT, ADWARE, AVG, online virus scans, system restore, nothing works - as well it might not considering my other computer cant send email from that specific account either. Any EXPERT help here??

Well its not actually affecting the computers per-say, just your profile in Outlook. Go through the settings of your profile and make sure nothing has changed. If it has, change it back and see what that does.
