Receiving contact form spam from my email address in Windows Live Mail
We have a contact form without a CAPTCHA on our site (currently being replaced in site upgrade). I often get spam emails which I don't open, move to Junk and then delete.
When I checked one just now (Properties - Details - Message Source), it was the usual spam message but my default email address was in the From field!!!
What's happening and what can I do about it?
Any help appreciated. Trying hard not to panic!
System: Windows 7, SP1
