Help with Flynax script

Need someone with knowledge of Flynax script. I set up an email on my ubuntu vps. My email is not working correctly and I need you to fix it and also set it up correctly in my Flynax script so when a new user signs up, the user gets a confirmation email. When the user wants to create a profile, some form fields are not showing, so I need you to help me with that.
I can pay you 20$ for this job.
