    Move all mailbox-to-mailbox (not command or file) aliases into virtual(5)
    and set:

            enable_original_recipient = no
            
    (but only if you don't need multi-drop mailbox support for downstream
    fetchmail domains).

    In our environments all 1-to-many (address to 1 or more addresses)
    expansions are done in virtual expansion, and aliases(5) is only used
    for delivery to (single!) commands or files.
