My wife has a yahoo account, and every so often, people get spam that looks like it came from her.
It isn't in her outbox, and the headers look like it came from Yahoo servers, but it does include contacts from her contacts list?
Do spammers harvest e-mails/passwords and then use the mail servers directly? Is that even possible with webmail, and is it a practice that anyone has seen?
I've advised her to change her password, but I was just wondering for general information.
