Thank you for the transparency regarding this communication. I saw that you omitted the name of the person that got in contact with you but you left his name on the e-mail. Perhaps it would be better to hide it as well.
This is really not good. With a little research, you get to the guy.
Yeah except he is an IRS agent, not a customer. He could post the whole email if he wanted to as its not really any sort of breach of confidentiality. He did the agent a favor by not leaving the email address in there.
