I'm not sending these e-mails; someone or something else is doing it.
Some things for you to check, see:
Why is Mailer-Daemon sending me a Failed Delivery message?
Who is the intended recipient? Since it's a Yahoo (i.e. spam central) account it's not particularly surprising that something went wrong, but if your account got "hacked" it's due to a weak password and/or weak security questions.
Agreed. Since Yahoo has a web-based interface, it doesn't necessarily imply that the mail app is compromised, since a web bot can send mail on its own if your password was compromised. Change your PW right away and see if the problem stops.
I'll third this. The same thing happened on my email account earlier last year. Changed the PW and Security Questions and the emails/spam stopped. As an added precaution to make sure a future incident would be isolated, I also went into the preferences and told the service to stop saving e-mail addresses I've contacted in the online address book, then deleted the addresses in the online address book. This way, if it does happen again, the spam bot won't target those I've contacted specifically, and hopefully be unable to send spam emails out at all (from what I gathered, the spambot that got a hold of my email account was only sending messages to people in the online address book, but I know that spambots don't always work like this).
How do I go about doing this?
Actually, since you're using Yahoo Mail, which doesn't appear to have that annoying feature other providers have, you shouldn't need to worry about it. I was just speaking in general when I said that. Aside from not using the web application to store contact info (I never recommend this personally), there's not much you can do. Regardless, if you use the instant messenger service, Yahoo will save some (I'm not sure why not all, but my account doesn't list all my contacts I keep in Adium, only some) instant messenger/email addresses on the web application. Unfortunately, if you delete them in the web application, they'll disappear from your instant messenger client as well, so I definitely don't recommend that.
i had the same issue with my gmail. at first i thought it was the mac mail that went bezerk.
however i logged into the gmail web interface (after many years) to find that the bottom bar said last login from china, and i am based in the uk.
none the less. first thing was to change my password and enable two step verification which is brilliant.
secondly went to vacation mailer settings and deactivated them. as they were activated and sending out mails automatically to folks that were on my list.
after that created a rule in mail that sent an apology to all those that received adverts to buy viagra from my mail address.
hope this helps.
p.s. enabled a self signed certificate in keychain access as well. all those folks that i mail frequently have accepted the certificate and it can only attach itself through mail from apple, not web based interfaces. so that its all safe and secure.
