How to change the domain from random generated emails in Faker Library using Robot Framework

I am using Faker Library to generate emails from some automation tests like a Register process. Can anyone tell me what file should I edit with the new email domain? Right now, all generated emails have @hotmail.com and I want that changed in something like mydomain.com.

I've manage to install the library, to import it in RIDE and to make a register process using random generated data, but like I said it will be nice if I could change the domain for random generated emails.

Thank you!
