Hello ! I am interested since few months in your services, and now i got my own domain. It is c4ff4r4tt1.com.ar , and i want to add that domain to use emails with that domain, like for example me : carlos@c4ff4r4tt1.com.ar 

Now the question... maybe it´s a simple question, and maybe not... sorry if it´s a noob question :(

.com.ar domains does not have functions to edit the mx properties or cname , or anything, so i placed it in zoneedit. 

So my question is: Can i use zoneedit to add / edit the cname or mx records so i can use my domain to have my mail, as i showed before?

Or what service you reccomend me? 

Or in the case it is impossible to do that ... is there any way i can proof that domain is mine? 

In that case i will give to you (administrators of ZoHo) all my data, or anything you want / need .

Thanks,  and have a nice day!
