My config for vacation messages, for what its worth, looks as follows
and only ever sends one reply to any specific sender address:

In routers I have:

vacation:
        driver = accept
        check_local_user
        require_files = $home/.vacation
        no_verify
        # do not send reply to errors or lists
        senders = "! ^.*-request@.*:\
                   ! ^owner-.*@.*:\
                   ! ^root@.*:\
                   ! ^postmaster@.*:\
                   ! ^listmaster@.*:\
                   ! ^mailer-daemon@.*"
        # do not reply to errors and bounces or lists
        condition = "${if or {{match {$h_precedence:}
{(?i)junk|bulk|list}} \
                        {eq {$sender_address} {}}} {no} {yes}}"
        transport = vacation_reply
        unseen


In transports I have:

vacation_reply:
        driver = autoreply
        file = $home/.vacation
        file_expand
        log = $home/vacation.log
        once = $home/vacation.db
        from = $local_part@???
        to = $sender_address
        subject = "Re: $h_subject"
        text = "Dear $h_from\n\n\
        This is an automatic reply.  Please feel free to send
additional\n\
        mail to me, as only this one notice will be generated. The
following\n\
        is a pre-recorded message, sent on behalf of\n\
        ${local_part}@???:\n\
        ================================================\n\n"
