I've setup the SMTP email settings according to the email arvixe sent me, and no emails are being sent that I can tell. I've checked junk mail, and I've waited the 24-48 hours. My domain is being hosted on Godaddy, but the Cheverteo install is on Arvixe.
SMTP Error: The following recipients failed: inbox@rodolfoberrios.com
I will recommend you to use http://mandrill.com/ to send emails. Email can fail by a thousand of reasons and if you want to make it work quick and easy use mandrill SMTP.
