I have created and set up everything.

On the mail service, whenever I try to send a new mail, no problem. I tried to answer this email, i got an error.

What did I do wrong?

tiago@brewdozer.com.br is the email address.

I also created a website (just did one template, nothing on it)

when I try to add into the DNS and i get an error:

O  record  que se quer adicionar conflita com o  record
www.brewdozer.com.br A 74.201.154.208

which means: the record you are trying to add conflicts with the record

What should I do now?
Is it a problem with my DNS server?

Thank you
