"anca" isn't a valid top-level domain name.

You can't simply make up names and expect mail to work; you have to  
add that hostname as an A record in a DNS domain you own or which is  
willing to add you (consider dyndns.org, or similar).  If you get  
your own domain, you should also set up appropriate MX records.

The other choice would be to look into FEATURE(nocanonify) and rely  
on a smart host somewhere which is willing to handle email on your  
behalf.
