Hi Marko
thanks for that clarification. That clears up why next_hop was not
evaluating to the domain. I don't have a mixture of local and virtual
mailboxes so for me using postfix local delivery via mailbox transport
(what I used to do with cyrus and with dbmail) was fine too and also
evaluates the local aliases file, though I could rewrite that to 
virtual_alias_maps...

However, it means the wiki documentation doesn't need changing: the
next_hop parameter is consistent with the rest of the instructions. It's
my setup that was different. If someone choses to do it the way I have
done, they can see the solution in the list archives.

thanks everyone.
