But if, as Wietse says, Postfix attempts to check the whole username first, then
user.double-barrelled@ would be delivered to user.doubled-barrelled@ and not user.name-delimited@ even assuming barrelled == delimited.
So in the worst case the guy delimiting his address to do folder sorting wouldn't get those mails. He should probably pick something more descriptive than a common surname though..
