Your mail system is not configured to serve lucasit.com. So when it gets mail for that domain, your mail system tries to send the message to another destination and gets upset when it finds that destination is itself. Try configuring mydestination with the name(s) of the domain(s) your mail server is to serve. It would also be a good idea to set myhostname to the real fully-qualified domain name of the host and have the system's hostname command -- ie the gethostname() system call -- also return that FQDN if it doesn't already do that.
