This week I had an email bounce back to me. The probllem is that I did not send the email. My send folder does not list that email either. I am pretty sure that someone is using my mac pro to send emails from me to thrid parties. All three of my credit card accounts have unauthorized charges on them. So my credit card info was compromised, and all records are protected by 1Password. Any suggestions on how I might prevent this from occuring in the future? I need a little this one.
