Thanks,

But I think if I use that then mails I send to anyone else in my isps 
domain will be rejected.
I want those mails to go to the default relayhost, which belongs to my isp.
Just for clarity, If an address is not in $mydestination or 
$virtual_mailbox_domains, I'm trying to get postfix to lookup the user 
and if it finds it then it uses dovecot lda, otherwise it uses relayhost.
I've signed up to the postfix mailing list so I'll see if they can field 
this one there.
