Not quite. You can usually find the IP address of the MAILSERVER it was sent from, which would usually be the mailserver of an Ineternet Service Provider. Sometimes you can narrow it down to a company, occasionally only, you can narrow it down to a specific IP on the ISP's network. With that the ISP theoretically can find out what account was used to send it, however they won't disclose that to you unless there is a legal reason compelling them to do so.
