Please post the lines that get added to the mail.log when you send an email to this account.

Additionally, I need to know the real "myhostname" from main.cf and the content of the /etc/mailname file.

Thats not ok. For email, you have to use a real existing hostname and it may not be identical with a hosted email domain. Use something like:

mail.yourdomain.com

where you replace yourdomain.com with a domain name that you own. Then make sure that the subdomain mail.yourdomain.com exists in dns and that it points with a DNS A-Record to the IP address of your server.

Mail working fine now.
