Ok that's weird
I went to reply to an email from a friend of mine through gmail and immediately got a 'message undeliverable' notice. I was confused, since what I'd done was hit 'reply' from within her email, which should have sent the message right back to the email address she'd sent hers from. I looked closer and the notice mentioned that the address that was undeliverable was 'upgrading1 at live dot com'. That is *not* my friend's email address. I looked it up, and it's apparently a phishing address. I went back to my friend's email and hit reply again, and this time paid attention to the pre-filled-in address. Sure enough, it was the upgrading1 address again. I had to manually replace it with her actual email address. I know her message wasn't a phishing attempt - she was writing to confirm our dinner plans for later in the week. So how did the phishing address get in the autoreply field? And what can I do about it?
