postmaster versus aliases

[Ark-man]

when i send an email to info@website.com, it gives me the error:

Final-Recipient: rfc822; root@website.com
Original-Recipient: rfc822;info@website.com
Action: failed Status: 5.4.6
Diagnostic-Code: X-Postfix; alias database loop for root

A fact is that in the /etc/aliases i have a string: "info: postmaster" thac could possibly cause all the issues; how can i change that?

i figured out, setting my personal email, problem is all emails are redirected to it, but i want to usa the info@website.com, how to prevent the mails to be sent to my email? i want to read the email from the website.com webmail
