I'm really confused about the MX Records and generally with email. I've set up Haraka SMTP server for outbound email delivery because I need to send sign up validation emails.
If I don't want to receive emails just to send them, do I need to setup MX records for my email server?

You are not required to have MX records just to send email.
However:
Short story: you don't have to have/manage MX records, but be sure to use a working email address as sender and be sure it is on a working domain with valid MX records.
