[vchkpw] domain to alias failure

[Remo Mattei]

Hello all I have a domain called xxyyxx.us and then the main domain 
which is an alias to the xxyyxx.us which is xxyyxx.com when I send an 
email to a mailing list to the .com it bouces back if I send it to the 
.us it works. Any suggestions?
Also the .us is expiring and I wonder if anyone has any suggestions on 
how to move those accounts from .us to .com

thanks
