I have my main email. I use it for work and stuff, set up in an account in Mail. However, I've recently discovered that the email people see as the sender in their inbox is a different email, my dad's email to be precise. Therefore when they reply, they are replying to my dad's email. What? How can this be possible. In the "from" portion of the email, my main email listed. How is it magically becoming my dad's email? Has anyone suffered a similar problem? These are all gmail accounts btw. This is so confusing and nerve wracking, since I need to send a lot of important emails to work, and when they respond, they're sending it to my dad instead. Help!
