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. John
