No! (But they can fake it..) Think of email just like regular postal mail. When you send a letter you write the address you are sending it to on the envelope. You also write where it's coming from - the return address. When someone sends an email, it's just like regular mail - they can write whatever 'return-address' they want. When the person gets the email they'll see what was written - it doesn't mean it came from that address of course.. This type of email abuse is called "spoofing" - and it's become fairly common. If you have a domain that spammers want to hide-behind, there not much you can do to stop it - but don't worry about someone actually using your account to send spam. We have an automated system that constantly monitors the email traffic to and from our servers, and anything that looks like spam is blocked immediately - and the owner of the account is notified. Just like a letter gets postmarked when it is sent through the mail - your email has "headers" that keep track of where the email has been. Headers are usually hidden by your email program since they take are fairly technical, but with some effort you can decode them and possibly see where the the spam actually came from.
