If you have a fairly recent version of Mail::Sender (0.8.08 or newer) you may use the skip_bad_recipients option: 

    skip_bad_recipients
        If this option is set to false or not specified then Mail::Sender
        stops trying to send a message as soon as the first recipient's
        address fails. If it is set to a true value Mail::Sender skips the
        bad addresses and tries to send the message at least to the good
        ones. If all addresses are rejected by the server it reports an "All
        recipients were rejected" message.

        If any addresses were skipped the "$sender->{'skipped_recipients'}"
        will be a reference to a hash containing the failed address and the
        server's response.
