Whats the difference between mailbox_transport key and virtual_transport key?In old examples I've seen virtual_transport used but it did not seem to work on my Ubuntu 14.04 system, whereas mailbox_transport definitely does.Is this a case of a changed api and looking at legacy/out-of-date examples?
Postfix virtual_transport vs mailbox_transport
postfix
mailbox_transport is a transport for local(8), while virtual_transport is the default delivery transport for virtual mailboxes.
